Martin Gräßlin 145f0c096f [kwin/effects] Do not use KActionCollections for the global shortcuts 
Most effects had a "collection" for one action. We don't need the
action collection, all it was used for is setting the object name.

With the removal of KActionCollection the effects do not need to link
XmlGui any more, though the dependency is still pulled in through
plasma.
