[wmx] better patch for to wmx to use mouse wheel

A better patch is to set quickflip True so using the wheel of the
mouse causes a quick flip.

With this patch, if you have a wheel mouse, 
* moving the wheel in the root window selects the next or previous
  channel
* moving it in the tab of a window moves that window up or down a 
  channel.
