events: Make the ungrabbed button press handling more bullet proof

Browse Source 
Instead of returning a value based on whether or not we handled it, we
have this logic: either we have taken a grab on the window, in which
case we have a grab op and have handled it ourselves, or we did not take
a grab and *need* to replay the event to the window.

Handle this in events.c by checking the grab operation in the same way
that we check the other grab ops.
