provide more onion services

Thanks for https://onion.torproject.org/

There are a few more services that could use an onion, these come to mind immediately:

• blog.torproject.org
• gitweb.torproject.org
• trac.torproject.org

Maybe someone(TM) should have a look at the DNS zone file and enter all yet un-onioned services.
