Fixed a bug in babystepping: The babystep value will be written to EEPROM

at the end of the menu only.
Provided a general method for a menu function to detect exiting by a timeout.
When exiting, the menu function is called with a global variable menuExiting set.
Some errorneously removed functions were reverted.
