application/problem+json and application/problem+xml should be considered as render-able types #347
Description
Since these two types are just plain JSON and XML respectively.

Also just a thought, should the warning be changed into "unknown Media Type"? Since Restfox doesn't really know if it's really a binary response. I think the response media type can be showed on the warning message too to let us easily decide if we should let Restfox render it.
