Rework/simplify chairAdjust - now using a class

- complete rework of chairAdjust.cpp/.hpp
  created a class cControlledRest which is more readable
  and saves a lot of duplicate code

- joystick.cpp: move chair control via joystick to
  chairAdjust.cpp (prevents dependency loop)
- button.cpp: fix bug instant idle when changing to ADJUST_CHAIR

Note: briefly tested this state on a breakout board:
Mode change and call of new class methods works.
