Adds the given owner name to this stub.  This is used to display all known clients of
the action represented by this stub.  Normally, when this class has actions, the names
of each action's owner would be used directly.  However, this class can also be used as 
a placeholder, when no actions have yet been registered.  In that case, the owner has 
to be set directly on this stub.
 
@param owner the name of the client that owns the actions that may get registered with
       this stub
