Martin Gräßlin 6cfdbfe1dc Remove compositing self-check 
Removes the last bits of the self-check at compositing startup.
It seems like they were only added to XRender because they were
in OpenGL and there they are not available for quite some time.

Also removes the now obsolete disable functionality checks from UI.
