Subject:    Patch: add "Lock Screen" key-binding

Hi,

the following patch adds a global "Lock Screen" key-binding (CTRL-ALT-L) and 
would close bug #24706.
My main concern is, if I break binary compatibility with adding the public 
slot slotLockScreen() to the workspace class. My latest tests didn't showed 
any problems with only kwin and kcontrol/keys/* recompiled, but I may be 
wrong.
Your opinions ?

Greetings,
Helge
