Implement kdedglobalaccel as a standalone demon.
The decision was made because beeing a kded module made it subject to the problems of all other kded modules.

If some module froze kded it could happen that the X frooze completely for some seconds or it seems like the alt-key is stuck.

Rename everything kdedglobal* to kglobal* for convenience.

This commit requires a recompile of at least kdelibs too. You will loose global shortcut on your next session login or kded/application restart.

If you want kcmshell4 keys to work again please recompile kdebase-workspace too.

This cmake code is supposed to delete the two files remaining from kglobalaccel being a kded moudle from your installation area.

If you encounter problems after recompilation please check if they were successfully removed.
