Porting the NETWM classes to xcb

[Rick Stockton]

In Qt, at/near line 66 of /src/plugins/platforms/xcb/qxcbwindow.cpp), they check to see if one of the #DEFINE macros from one of the newer, divided-util XCB 'include' files had been defined. (It's not defined until after the util packages were split.) Maybe that would be shorter, easier than a big 'FIND_PACKAGE' search?
