Add airplane mode feature

Implements 'Airplane mode' feature to disable and enable bluetooth/ble
Adds airplaneMode as a non-persisted setting
Adds a setting menu for switching airplane mode on and off
Displays an airplane symbol on the Digital watch face and the
    PineTimeStyle watch face when airplane mode is enabled
Always enables bluetooth/ble on boot (disable airplane mode)
Alphabetizes the settings menu options
Style cleanups

Closes #632
