- LeapSDK integration: Implemented the remaining gesture events for the Leap Motion. Also cleaned up the ActionMap::processAction() function by creating the following new funcitons:

ActionMap::processGesture
ActionMap::processTouch
ActionMap::processButton
ActionMap::processMove
ActionMap::processMotion

The ActionMap::processAction function is now very clean, as it only has a switch statement based on the input event's action member. That will filter and call the correct processing function. This should make it a little easier to add new events in the future.
