The X11 libraries are now in include/X11 folder, instead of include
folder. Now is possible to compile the application in new systems.
This patch changes the wmbutton version in the README file too.
Based on Christian Aichinger's patch.
The original wmbutton 0.6.1 is added to the repository.
wmbutton is a dockapp with nine buttons (3x3), capable of launch 27
different applications using the left, middle and right buttons.
