DeleteRating doesn't return the view

[zjs2k]

After hit the delete button to delete a rating, the whole rating star view disappears. It is simply because the deleteRating method is not returning the view:

plone.contentratings/plone/contentratings/browser/ajax.py

Line 39 in 18937e5

self._call_view_method(category, 'remove_rating')

It should be:
return self._call_view_method(category, 'remove_rating')
