Add new endpoint to return everything the annotator view needs for types, etc.

Instead of calling Project, Membership, Versions, LocalizationTypes,StateTypes as individual calls, with the same arguments, we should create 1 REST endpoint that returns all the information in one request.

In the multi-page, we could likely further combine to call it once for all media and subdivide accordingly.

An approach that could be exciting is a daisy-chain endpoint which allows other endpoints to be called in sequence from the daisychain endpoint. This eliminates round-trip times and overheads associated with connection intialization on data that need not or can not be parallelized. Another use of this endpoint could be multiple-data multiple-operation (e.g. bulk sets where each row gets its own value)
