More cleverness in midend_process_key()

It now strips off modifier flags from keys that shouldn't have them and
maps printable characters with MOD_CTRL to the corresponding control
characters.  It also catches Ctrl+Shift+Z because that obviously belongs
in the midend.

I've updated the JavaScript front-end to take advantage of these
changes.  Other front ends are unchanged and should work just as they
did before.
