I'm using Travis-CI, so remove tox config.
Add a helper for retrieving the newest Tip.
Add a utility module for common helper code.
Use the utility module's extract_publication_date logic.
Add dependency on requests (I'm about to use it in manage.py).
Add a manage.py to execute utility-type stuff.

The first thing I added to it was a command to poll twitter for newer
tips and update the DB with them.
