Moving KRatingWidget from Nepomuk to kdeui

so today I ported knewstuff3 over to use the KRatingWidget from kdelibs.
I have some minor problems that would be easy to solve with some additional 
api in KRatingWidget.

Some items we have in knewstuff do have a rating but you cannot vote for it.
Currently the KRatingWidget will always be clickable, it would be nice, if I 
could add an "enabled" property (getter + setter) to the class.

The other problem I ran into was that the setter for the current rating will 
always emit the changed signal. So there is no way to easily use this widget 
in a KWidgetItemDelegate as I'm trying in knewstuff.
Adding a signal that is only emitted when the user actively changes the 
rating would be trivial. The old version I had copied to knewstuff did not 
show this behavior.

I would like to implement the suggested functions, unless someone suggests a 
better way.
