- config, chairAdjust:
- disable reset-pin of display (not connected, random pin was assigned)
same pin was used for chair adjust resulting in on state after startup
- fix chairAdjust not stopping in OFF state
- display
- add functionality to show different status screens (content when not in MENU)
- add status screen 'Speed' (to show speed and debug speedsensors)
- menu
- fix item joystick define center not working
- add item to select status screen
