Lucas Murray 752d5fa642 Extracted mouse polling out of the composite timer to allow effects to
detect mouse movement and modifier key changes even when KWin is idle.
As the track mouse effect requires polling to always be active disabling
it by default to prevent wasting CPU usage in the default install.
