- Added slugify function that will allow us to build slugs from the text field.
- cleaned up some of the forms for adding blogs.
- Database column and defaults clean up.  I have also deleted all of the old migrations and created just one since this is the initial table creation.
- Added back the is_authenticated check on the admin views.  I had this turned off for testing.
- Bug in the session creation on the LoginForm.  I had the old nickname column which I changed to user name.
