jhenrique09 edits: make it DUI independent

Original commit message:
Same robust action library as used on software navigation. Supports
single tap, double tap, and long press. As a precautionary measure,
single tap back and single tap home are fixed and can not be changed.
Camera button actions are not supported at this time. We will bring
in wake key support at a later time.

Also includes:
