We should have an Apache theme, which:
- sets the footer contents (currently done in master theme in [#7274])
- hide 'brought to you by'; or maybe a config option for that (currently done via CSS at /p/_admin/overview)
- sets the logo (currently done via css/js hack at /p/_admin/overview)
- possibly have better placement of required License, Sponsorship, Thanks, Security, Apache.org links. Maybe a separate menu line? If we have other projects on the site, they would need those links too - although potentially need to customize them.
- override home page content?
