Display class gets access to App interface and HmRadio
Display class prepares relevant online information for displays in new DisplayData structure
Displays get pointer to DisplayData and only use information received from there
- rework display type handling: remove uneeded checks because defined context from which functions are called
- default initialize "mMono" pointer (potential illegal memory access)
- define EXACTLY one display type for ePaper display (type 10). There is no need to use ranges and distinguish oled from epaper display. Simply one switch/case
- correct type handling for display type (javascript). Event handler gives a string instead of number (display type)
* further improved save settings
* removed `#` character from ePaper
* fixed saving pinout for `Nokia-Display`
* removed `Reset` Pin for monochrome displays
