Trackball and generic motion events now pass through the IME in case
it would like to handle them before passing them on to the view

While I was at it, I also...
...fixed the documentation on InputMethodService.onKeyUp()
...added documentation to InputMethodService.onTrackballEvent()
...added trackball and generic motion events to the "input" command
...fixed input consistency verification involving ACTION_OUTSIDE
