Peter Hutterer 17bbcad280 Revert "Add another third state to TouchpadOff for disabling all but button clicks" 
This third state is not needed, the behaviour of the touchpad driver is now
good enough to not need an external syndaemon instance to toggle this third
state.

This reverts commit eea7335876.
