patch: dpms
This patch interacts with the Display Power Management Signaling and
automatically turns off the monitor after a configurable time. The
monitor is reactivated by a keystroke or moving the mouse.
The time until the monitor is disabled is configurable as monitortime in
the config.h file in seconds.
This is a modified version of the patch from suckless.org which permits
normal timeout values of zero.
