Add functional menu items (accel/decel), Add menu-timeout

menu.cpp:
    - add item center-Joystick (functional)
    - add item accel-Limit (functional)
    - add item decel-Limit (functional)
    - fix display freeze on timeout
    - add menu timeout
    - switch to previous mode on exit instead of always idle

motorctl.cpp:
    - add getFade method, to get currently configured values
    - add log output on fade change
