Added an install sequence to initialize a DB, add a site administrator, and import the initial site content.
Fixed handling of --debug in the argument parser.  --debug can now be used without supplying a truth value.
Supplied the correct base URL for the Tumblr API.
Now ignoring .pyc files.
Finished code for user login and OAuth token handling, as well as the installer sequence.  TODO: add current_user.is_active() to template globals, and use that instead of session.LOGGED_IN
