Change the behaviour of remotable concern. Previously, it would skip
downloading an attachment if the stored remote URL is identical to

actually currently stored by Paperclip.
* Move ApiController to Api/BaseController
* API controllers inherit from Api::BaseController
* Add coverage for various error cases in api/base controller
* Redirect to streaming_api_base_url
When Rails receives a request to streaming API, it most likely
means that there is another host which is configured to respond
to it. This is to redirect clients to that host if
`STREAMING_API_BASE_URL` is set as another host.
* Use the new Ruby 1.9 hash syntax
