motorctl, currentsensor:
- add config option for inverted current sensor
- adjust loglevels
config:
- Adjust gpio pins to actual wiring (not breakout board for testing)
- Add min pulse durations for speedsensors (measurements with scope)
- Adjust config to currently mounted encoders
control, buzzer:
- adjust beeping
- Add feature for optinal delay to buzzer class:
have some pause after beeps instead of immediately
continuing with next queued sequence
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
