To assign no shortcut to the action using the keyboard shortcut gui.  In your 
scheme, this would require KShortcut or KAction to distinguish between empty 
and null.

1) User doesn't want a shortcut for the action (eg. doesn't want to 
accidentally trigger it).  I use this to turn off some kdevelop shortcuts I 
don't like.

2) User wants to use the shortcut for a different action.  KDE needs to assign 
no shortcut to this action in order to assign the shortcut to the other 

So, either we add unsetCustomShortcut() to KAction (and make KAction track 
whether it has been defined), or KShortcut gets a distinction between empty 
and null, or we leave things as is (with perhaps some naming changes).
