Subject: [PATCH] Explicitly set contentType in Firefox's Request

The default value is `"application/x-www-form-urlencoded"`, but we
usually want JSON. In some versions of Firefox, passing `{headers:
{"Content-Type": "application/json"}` to the Request constructor works.
However in other versions, such as the latest Developer Edition 51.0a2,
the actual header sent erroneously becomes `Content-Type:
application/x-www-form-urlencoded, application/json`. This breaks XCloud
and might break other services as well.

This patch simply ensures that if we ask for `application/json`, we get
`application/json`.
