Tests for PUT have been added to check for expected behavior.
Attempting to PUT multiple EncodedVideos with the same profile
will return an error.

Other notes:

POST for EncodedVideo implemented. Can now upload a single Video
with multiple EncodedVideos with profile_name as it's profile.
Cannot do any bulk operations. Serializers have been simplified.
Views are now using genericviews. Queries are now being tracked
in a few tests.

EncodedVideo part of the upload. Complete EncodedVideo dicts may
now be uploaded. Rejects all EncodedVideos of a Video when there is
an invalid EncodedVideo. Does not reject other Video when a differet
Video is invalid. Currently, EncodedVideo cannot be updated, they can
only be created.

Other notes:

Initial part of the upload portion of the API. Video Models can
