Fix keyboard problems introduced in improvements 

Handling of a lot of ordinary keys was broken, e.g. number row and
non-alphanumeric keys, especially with Shift.

I think what's broken has been fixed, but have reverted the improvement
that Controller/vector is only called once per keypress. Many keys cause
Controller/vector to be called twice, but only once with Controller/key
nonzero.
