Title: Add support for Rackspace's Extract Archive API call

See http://docs.rackspace.com/files/api/v1/cf-devguide/content/Extract_Archive-d1e2338.html
for documentation on the API call.

@elight had the key insights that helped with this, and @jnoller let me know of the existence of Extract Archive.
