Subject: Xinerama and XRandR dual head support for cwm(1). Now we detect the
 xrandr reconfiguration events and change our sizes depending on that. We also
 detect the xinerama screens for maximize, vertmaximize and initial window
 placement.

This could be improved by automatically resizing maximized windows when
the screen resolution changes and by moving windows that would be hidden
into visible space. Said changes will come shortly.

Tested by many. matthieu@ didn't oppose.
