Login templates

Basic blocks, specifically fully working login, registration, image, and content blocks. Specified blocks are working except for:
- I think the CSS needs moved. 
- Default fixtures.
- Tests.
- Easy to use admin.

Please review.

**Important Note**: All html is assume safe. This is probably not non-very-very-trusted user friendly.
I was under the impression that django expected a request object, not a None. If not, this is a neat trick. Remind me to check this out if this is the case, because if it is legit I could have used this when working on multiple locations.
