Tweaked a few dependencies in preperation for adding south migrations
Added south_migrations for all apps with models
Django 1.6 is working with the Demo app. Though still needs cleanup.
 * Got the south_migrations for Django 1.6 applying.
 * The djangoandablog ones still need to be made more generic.
 * Fixed a needless url diferentiation between 1.6 and 1.7.
 * Fixed the build.py loadalldatas to work with both 1.6 and 1.7 (1.6 does not support globs)
 * Fixed some missing settings for allauth.
Django 1.6 migrations custom user model compatibility:
 * Updated south migration to not have user model hard codes
 * Added a new test_venv task to build.py
 * Updated settings to disable south migrations durring test run
 * Removed coverage functionality because it was having trouble with
   Django1.6 and python 3.3.
