ARI: Add the ability to download the media associated with a stored recording
This patch adds a new feature to ARI that allows a client to download
the media associated with a stored recording. The new route is
/recordings/stored/{name}/file, and transmits the underlying binary file
using Asterisk's HTTP server's underlying file transfer facilities.
Because this REST route returns non-JSON, a few small enhancements had
to be made to the Python Swagger generation code, as well as the
mustache templates that generate the ARI bindings.

URIs are done.
+ * Stored recordings now allow for the media associated with a stored recording
+ to be retrieved. The new route, GET /recordings/stored/{name}/file, will
