- Accidently created the tags table as a One-To-Many instead of a Many-To-Many.  I have fixed this up as well as any references to it.
- I had to redo the migrations because they did not work properly because of the model change.  This is ok at this point since we are still not released yet.
- Removed categories list from the template.  This isn't needed right now so we will push this off until after the initial release.
- Added function to retrieve list of articles by year, month and day.  This is a good way to present archived articles.
