During finger configuration transition, as well as after a tap,
there would be no tentative gestures registered in the instantiator,
leading to faulty emission of motion events. Fixed with this patch.

Add the five first contacts to the property list, and unify the
handling of all gesture types in this regard. To avoid duplication,
move the scaling of properties closer to the gesture recognizer.
Move all gesture event handling code to grail-event.c, simplifying
the structure somewhat.

To be able to model touch information uniformly across all supported
devices, the semantics of the touch attributes has to be treated
explicitly. Drop the generic touch property array and replace it
by an actual structure. In addition, the touch-engine abstraction
turned out to not be needed, so drop it as well.

By calling the grail_set_bbox(), grail will do translation of api
coordinates and matching properties to an external coordinate system,
such as screen coordinates.

For transient gestures like taps, use update only.
