Modular approach - first version for main branch (#60)

* first version of "modular-approach" * changed keyboard commands for HOME and BACK * Update README.md * only some typos in comments * readability * comment for what the mqtt keyboard is used * removed numbering of tab variables. not needed anymore * changed the default keyboard from "´mqtt keyboard" to "BLE keyboard" * updated to latest version of keypad library from Github, changes for inverted logic are explicitely marked * added comment for key repeatModes * added comment for MQTT keyboard * setting timout via GUI now works, not only dropdown without functionality * BLE indicator added; separation of BLE/WiFi activation from activation of devices using it * report battery level to BLE device * Dynamic keyboard commands, so you can safely deactivate BLE and/or WiFi and not break the example code * reorganized files into folders * moved lv_conf.h into the gui folder * added devices for appleTV and smarthome * assets.c broken up and placed them where they are used * added support for IR RC5 * reorganization of files and folder * added comment * renamed assets files * introduction of gui_registry * removed unnecessary functions from sleep.h * use gui_registry.h only once * some files renamed for better understandability * minor renaming * some more renaming * check if WiFi label was instantiated before using it * introduction of a scene registry * save prefs directly after timeout is changed * renaming of preferencesStorage * comment added * only readability * detailled definition of key layout for the diferrent scenes * made code compile for "device_smarthome" when WiFi is deactivated * fixed access violation when no scene was active * added support for IR DENON commands * increased lvgl heap from 32K to 48K

+# ESP32 BLE Keyboard library
+
+This library allows you to make the ESP32 act as a Bluetooth Keyboard and control what it does.  
+You might also be interested in:
+- [ESP32-BLE-Mouse](https://github.com/T-vK/ESP32-BLE-Mouse)
+- [ESP32-BLE-Gamepad](https://github.com/lemmingDev/ESP32-BLE-Gamepad)
+
+
+## Features
+
+ - [x] Send key strokes
+ - [x] Send text
+ - [x] Press/release individual keys
+ - [x] Media keys are supported
+ - [ ] Read Numlock/Capslock/Scrolllock state
+ - [x] Set battery level (basically works, but doesn't show up in Android's status bar)
+ - [x] Compatible with Android
+ - [x] Compatible with Windows
+ - [x] Compatible with Linux
+ - [x] Compatible with MacOS X (not stable, some people have issues, doesn't work with old devices)
+ - [x] Compatible with iOS (not stable, some people have issues, doesn't work with old devices)
+
+## Installation
+- (Make sure you can use the ESP32 with the Arduino IDE. [Instructions can be found here.](https://github.com/espressif/arduino-esp32#installation-instructions))
+- [Download the latest release of this library from the release page.](https://github.com/T-vK/ESP32-BLE-Keyboard/releases)
+- In the Arduino IDE go to "Sketch" -> "Include Library" -> "Add .ZIP Library..." and select the file you just downloaded.
+- You can now go to "File" -> "Examples" -> "ESP32 BLE Keyboard" and select any of the examples to get started.
+
+## Example
+
+``` C++
+/**
+ * This example turns the ESP32 into a Bluetooth LE keyboard that writes the words, presses Enter, presses a media key and then Ctrl+Alt+Delete
+ */
+#include <BleKeyboard.h>
+
+BleKeyboard bleKeyboard;
+
+void setup() {
+  Serial.begin(115200);
+  Serial.println("Starting BLE work!");
+  bleKeyboard.begin();
+}
+
+void loop() {
+  if(bleKeyboard.isConnected()) {
+    Serial.println("Sending 'Hello world'...");
+    bleKeyboard.print("Hello world");
+
+    delay(1000);
+
+    Serial.println("Sending Enter key...");
+    bleKeyboard.write(KEY_RETURN);
+
+    delay(1000);
+
+    Serial.println("Sending Play/Pause media key...");
+    bleKeyboard.write(KEY_MEDIA_PLAY_PAUSE);
+
+    delay(1000);
+    
+   //
+   // Below is an example of pressing multiple keyboard modifiers 
+   // which by default is commented out. 
+   // 
+   /* Serial.println("Sending Ctrl+Alt+Delete...");
+    bleKeyboard.press(KEY_LEFT_CTRL);
+    bleKeyboard.press(KEY_LEFT_ALT);
+    bleKeyboard.press(KEY_DELETE);
+    delay(100);
+    bleKeyboard.releaseAll();
+    */
+
+  }
+  Serial.println("Waiting 5 seconds...");
+  delay(5000);
+}
+```
+
+## API docs
+The BleKeyboard interface is almost identical to the Keyboard Interface, so you can use documentation right here:
+https://www.arduino.cc/reference/en/language/functions/usb/keyboard/
+
+Just remember that you have to use `bleKeyboard` instead of just `Keyboard` and you need these two lines at the top of your script:
+```
+#include <BleKeyboard.h>
+BleKeyboard bleKeyboard;
+```
+
+In addition to that you can send media keys (which is not possible with the USB keyboard library). Supported are the following:
+- KEY_MEDIA_NEXT_TRACK
+- KEY_MEDIA_PREVIOUS_TRACK
+- KEY_MEDIA_STOP
+- KEY_MEDIA_PLAY_PAUSE
+- KEY_MEDIA_MUTE
+- KEY_MEDIA_VOLUME_UP
+- KEY_MEDIA_VOLUME_DOWN
+- KEY_MEDIA_WWW_HOME
+- KEY_MEDIA_LOCAL_MACHINE_BROWSER // Opens "My Computer" on Windows
+- KEY_MEDIA_CALCULATOR
+- KEY_MEDIA_WWW_BOOKMARKS
+- KEY_MEDIA_WWW_SEARCH
+- KEY_MEDIA_WWW_STOP
+- KEY_MEDIA_WWW_BACK
+- KEY_MEDIA_CONSUMER_CONTROL_CONFIGURATION // Media Selection
+- KEY_MEDIA_EMAIL_READER
+
+There is also Bluetooth specific information that you can set (optional):
+Instead of `BleKeyboard bleKeyboard;` you can do `BleKeyboard bleKeyboard("Bluetooth Device Name", "Bluetooth Device Manufacturer", 100);`. (Max lenght is 15 characters, anything beyond that will be truncated.)  
+The third parameter is the initial battery level of your device. To adjust the battery level later on you can simply call e.g.  `bleKeyboard.setBatteryLevel(50)` (set battery level to 50%).  
+By default the battery level will be set to 100%, the device name will be `ESP32 Bluetooth Keyboard` and the manufacturer will be `Espressif`.  
+There is also a `setDelay` method to set a delay between each key event. E.g. `bleKeyboard.setDelay(10)` (10 milliseconds). The default is `8`.  
+This feature is meant to compensate for some applications and devices that can't handle fast input and will skip letters if too many keys are sent in a small time frame.  
+
+## NimBLE-Mode
+The NimBLE mode enables a significant saving of RAM and FLASH memory.
+
+### Comparison (SendKeyStrokes.ino at compile-time)
+
+**Standard**
+```
+RAM:   [=         ]   9.3% (used 30548 bytes from 327680 bytes)
+Flash: [========  ]  75.8% (used 994120 bytes from 1310720 bytes)
+```
+
+**NimBLE mode**
+```
+RAM:   [=         ]   8.3% (used 27180 bytes from 327680 bytes)
+Flash: [====      ]  44.2% (used 579158 bytes from 1310720 bytes)
+```
+
+### Comparison (SendKeyStrokes.ino at run-time)
+
+|   | Standard | NimBLE mode | difference
+|---|--:|--:|--:|
+| `ESP.getHeapSize()`   | 296.804 | 321.252 | **+ 24.448**  |
+| `ESP.getFreeHeap()`   | 143.572 | 260.764 | **+ 117.192** |
+| `ESP.getSketchSize()` | 994.224 | 579.264 | **- 414.960** |
+
+## How to activate NimBLE mode?
+
+### ArduinoIDE: 
+Uncomment the first line in BleKeyboard.h
+```C++
+#define USE_NIMBLE
+```
+
+### PlatformIO:
+Change your `platformio.ini` to the following settings
+```ini
+lib_deps = 
+  NimBLE-Arduino
+
+build_flags = 
+  -D USE_NIMBLE
+```

+Credits to [chegewara](https://github.com/chegewara) and [the authors of the USB keyboard library](https://github.com/arduino-libraries/Keyboard/) as this project is heavily based on their work!  
+Also, credits to [duke2421](https://github.com/T-vK/ESP32-BLE-Keyboard/issues/1) who helped a lot with testing, debugging and fixing the device descriptor!
+And credits to [sivar2311](https://github.com/sivar2311) for adding NimBLE support, greatly reducing the memory footprint, fixing advertising issues and for adding the `setDelay` method.

+// The downside of a large timeout value is a lot of less complex protocols

+// them is often also around 20+ms. This can result in the raw data be 2-3+
+// times larger than needed as it has captured 2-3+ messages in a single
+// capture. Setting a low timeout value can resolve this.
+// So, choosing the best kTimeout value for your use particular case is

+// The downside of setting this message too large is you can miss some valid
+// short messages for protocols that this library doesn't yet decode.
