Hello hello

Changes
======
- I rearranged the files to make porting more straightforward.  I added imports in the package file(feedgenerator/__init__.py) to try to keep some bw compatibility but I'm not sure how many people are using this right now, we might just drop them?
- Then I updated to the latest django.
- I also ported the geo mixin class.
- I applied some fixes/changes from webhelpers.
- I added some paperwork.
- I added some basic tests to make sure the fundamentals work, although the code is more completely tested with django's test suite.

TODO
======
- Versioning
- Basic documentation, ie. README.txt

Tell me what you think.
