Replace touch logic with utouch frame engine

The original grail uses an internal touch framework and exports some
touch information as extended attributes to gesture events. This was
never quite the intention, but rather to expose gestures and touches
on a similar footing, such that grail can be input agnostic. This
patch starts off by replacing the internal touch framework with the
utouch-frame engine.
