initial support for haptic feedback

initial support for haptic feedback

[Bill Filler (bfiller)]

this works, but will give haptic feedback instead of audio feedback if the audio feedback setting is turned on.

TODO:
- make haptic feedback it's own setting
- make haptic/audio mutually exclusive
- add haptic setting switch to settings panel.
