Instagram Video post handling, plus improved Places support (Nest and TripIt).

This release handles Instagram Video posts properly, downloading the source video file and hosting it locally. New post captions will also be parsed for username references, and linked up as People.

It also adds Places support to the Nest and TripIt importers, creating/associating places for the structure and camera location (Nest) and for every airport involved in a trip (TripIt).

Also fixes a problem where the Twitter importer was mangling newline characters, and adds a reprocessor that you should run over your old tweets to fix previous issues.
