* FEATURE: Onebox can match engines based on the content_type `FinalDestination` now returns the `content_type` of a resolved URL. `Oneboxer` passes this value to `Onebox` itself. Onebox engines can now specify a `matches_content_type` regex of content_types that the engine can handle, regardless of the URL. `ImageOnebox` will match URLs with a content type of `image/png`, `jpg`, `gif`, `bmp`, `tif`, etc. This will allow images that exist at a URL without a file type extension to be correctly rendered, assuming a valid `content_type` is returned.
