* Added session auth to the Media API (if you're logged in)
* Started reworking our Plupload interaction with the server to be less
awkward.

aren't dispatched to airtime_analyzer yet (coming next...)
* Basic HTTP reporting back to the File API works (PUT)
* Use the database table names as JSON field names.
* Fixed result returning bug in message_listener.py
* Fixed API key verification to adhere with the HTTP Basic Auth spec
