[PATCH weston] input: don't send to clients key events eaten by bindings

[Bill Spitzak]

I really can't imagine this is a problem, and clients may even expect 
the current behavior. It certainly is expected for shift keys: if I 
alt+tab to a program it acts like alt is still held down. A quick test 
on Ubuntu shows that a program you alt+tab to gets a map with both alt 
and tab held down.

Does this have something to do with preventing the key from repeating?
