Add django-wiki
Implement django-wiki as a replacement for mediawiki. This is not
on a subdomain. Access is only available for logged in users. Sign
ups are disabled.
Fix Some Timezone Warnings
I previously enabled USE_TZ to support django-wiki. This change fixes
up some warnings as a result of that. There are still warnings around
class based date views. Those can't be fixed.
