Fix slow buffer paste

Was caused by updating all buffer hooks on every char insert.
Particularily, the syntax update takes a little bit too long to
call on every char. Now the keyboard parsing routine compresses
all consecutive self-inserting chars into one "key press".

Also fix some small issues with timers and update them with a min
and max.
