Add menu vibration
This merge request
- add vibration to the menu
smooth_vibrationmodule for introducing common vibration patterns/mode
I've basically experimented a bit with coming up with ways to trigger the vibration motor.
This is super primitive.
- menu timeout doesn't trigger timeout vibration
- more sophisticated patterns for vibration motor possible?
- should we have different vibration modi for going up and down
- could we add a vibration mode for when you cycled through the entire menu maybe?
- is the select vibration acceptable
- (how) should we make vibration configurable?
