Merge remote-tracking branch 'origin/staging' into brightcove
Moved code to get DFXP for all languages into the Video class
Added code to handle the brightcove API for syncing
Hooked the Brightcove API code into the syncing system.

I think brightcove syncing is now working.

Also refactored the code to create kaltura/brightcove videos for the
test.  Using factoryboy is much nicer and can be used by other cases
as well.
