Rip out mysql

MySQL is needed only for google auth tickets. But google presentation doesn't
work anyway, so I'm pushing this back in to ease our buildout, but it doesn't
actually fix it.
Remove last uses of mysql
Clean up html a little, disable google presentations.

The html is still horrible, but at least it no longer abuses line
breaks in the way it did.
Merge branch 'mysql-cleanup' into testing
