Fix app behaviour on Xinerama displays

Browse Source 
With Xinerama, on heads other than the primary, certain parts (menus,
scrollbars) of certain types of clients (Qt) are incorrectly or not at
all drawn.

The fix follows other window managers in completely ignoring the
_NET_WORKAREA property.

Problem originally poked at by Ambrus Szabo, correct keyword and the
eventually implemented solution suggested by Lucius Windschuh, typed
up by me.
