diffcore-rename: similarity estimator fix.
The "similarity" logic was giving added material way too much
negative weight. What we wanted to see was how similar the
post-change image was compared to the pre-change image, so the
natural definition of similarity is how much common things are
there, relative to the post-change image's size.
This simplifies things a lot.
