Add separate database table for LaTeXML (step 1)

Currently the PNG and the LaTeXML rendering mode
use a common table in the database. If both rendering
modes are allowed in a wiki simultaneously this causes
problems, because the fields are continuously overwritten.

This change adds a new table for the LaTeXML rendering mode
to the database.
