Fixes to Exfoliation theme

Moved pnpSelected and dataSelected from extinfo.css to common.css since
more than just the extinfo pages use this CSS. Particularly, the
bookmark popup which now looks a lot better with this change.

Removed table.stateInfoTable1 th and th.data CSS from common.css since
most of this actually gets overridden in extinfo.css and I have not
found any problems with removing it thus far.
