Added functional menu using display and encoder:
- a menu item is defined in one struct
- scroll in a list of defined items
- select option
- modify value
- save value, return to list
Currently only menu is run (button and status display disabled)
- Add menu.cpp/hpp
- Add encoder.cpp/hpp mostly from previous test in board-control
- display.cpp: only run new handleMenu() function
- main.cpp: initialize encoder at startup, disable button task for testing
