Currently testing with breakoutboard and larger
1.3'' display (OFFSETX needed)
- display.cpp:
- change structure (outsource in page functions)
- add git and compile info to startup screen
- add armchair mode and motor current to status screen
- control.hpp: Add methods to get current armchair control mode (string)
- motorctl.hpp: Add method to get motor current
- make motorctl compatible with different drivers
- pass set function instead of specific motor object
- add lambda function in config.cpp
- update config to use one new sabertooth driver instead of two single100a
- main test controlled motor
since board_single uses mostly the same code as board_control and
board_motorctl several files are outsorced to common folder to prevent
dupliate code and different versions
