Add new focus model: StrictMouseFocus

This is not actually implemented yet, but from now on, "MouseFocus" means:
  Focus follows mouse only when you are moving the mouse, any EnterNotify events
  caused by non-mouse operations (window closing, keycommands, changing
  desktops) will *not* shift focus

And once fully-implemented, "StrictMouseFocus" will mean:
  Focus follows mouse on every EnterNotify event (except when the "ClientMenu"
  closes or during alt+tab window cycling)
