Merge pull request #13 from scj7t4/develop

Fixing some rows I missed in the login view
Tigtened up blog settings to prevent comments and whatnot
Now comments and pingbacks should be blocked.

Was looking at the dev documentation...
Pinned down versions in buildout.cfg.
Use siggame fork of zinna-theme-bootstrap
Updated buildout.cfg to install gunicorn_django by default
Wrote a django management command to update TeamClients

Iterates all TeamClients, pulling each one's base repo, and pushing
back to client
Changed .wait() calls to .communicate() and added a little more output
Only show diff stat... full diffs are far too long.
Fiddled with navbar tabs a little.

Ditched the blog and about-us tabs and added a "SIGGame" tab, which
has dropdown links to the blog and about-us stuff.
Added a flatpage template with no page header
