Martin Gräßlin 42dfdb63b0 Global Shortcut support for KWin scripts and scripted Effects
A global method "registerShortcut" is exported to the scripts which
can be used to register a callback to be called when the global
shortcut is triggered.

The shared code between Scripts and Effects is moved into template
functions defined in a new file scriptingutils.h.
