Rewrite most of grab_menu in grab.c (it was partly 9wm code).

This should work functionally the same, with a few simplifications.

Changes:
- we don't care if you're holding another button when you release the
  menu key if you don't want to select anything, move off the menu.
- remove the hysteresis from the menu selection (before you had to move
  more than three pixels onto a new menu entry before it selected it)
- simplify a lot of the selection code
- kill dead code.
- do what the XXX comment said and cache the screensize (i may tweak
  this later).

As far as I can tell, the only code remaining from 9wm is the list of
fonts in calmwm.c. Others appear to concur.

ok marc@, looked over and tested by a few others. Reminders from okan@.
