[x11] Warp the mouse when it touches a barrier

Browse source 
It seems that the mouse escaping the barriers requires some combination
of hitting two at once, and holding your mouth just right (something
about sliding the mouse up and down one barrier near the other).
However, sending the mouse back to the center of the screen when it
touches a barrier makes such sliding impossible.

This seems to fix #38
