Redoing how mobile handles tables

Removing several resets, adding support for wikitable class. This
fixes hieroglyphics, cladograms, family trees, and other cases where
tables are used to control formatting, while keeping most other
tables looking pretty.

Also restyling infoboxes per design input.

Beta only for now.
