* Using the url_processed case handler to implement a workaround for ARTstor timed token urls.
* ARTstor urls are requested via their JSON api and cached for an hour. (Key'd by the ARTstor ID). (Note that CU domains are whitelisted by the ARTstor servers)
* Also repointing old items that have no ARTstor ID mapping to the non-authenticating server on ARTstor's side. This is a temporary workaround until we can map needed items.
* Removing any changeable information from compress sections. (let's just say, i'm an idiot...)
* Removing all old revision cache-busting code -- templatetag, pre-commit release_id generation, template references, url additions
* A little selenium test port over from the develop branch to ensure the tests run well.
analytics references are in the wrong place.
Summary collection items need url processing too.
Updating sherdjs to pull in the vimeo fix.
