Fixes #167, "Rhinestone Review display is screwed up".
The immediate problem was that there were two styles defined for perfhover, and they didn't give enough leftward shove to hide some of the performer bios.
(reasons for this are probably interesting - I suspect it's got to do with either images or bios of some particular performers, particularly Bella Blue and Red Velvet
and Rasa Vitalia)
Fixed by killing one of the (mostly identical) definitions for that class, and adding another 9 to the leftward shove.
