Video State Synchronization

[Remi Broemeling]

As one of the last major things remaining, we need video state to properly synchronize between the database and the browser-side cache. In general what we want is:

• The browser cache keeps track of when the last time that it did a synchronization with the master server is. On each page load (can be repeated every X hours), the browser polls the server for video states that have been updated since this timestamp.
• The server needs to record the "updated_at" time of each video state, so that it can answer the above query.
