Hypermedia handling

[chriskapp]

REST APIs sometime include links to other resources i.e.

it would be great if we could add some more support to resolve those links. With the client SDK you are not able to resolve those links since you have a specific client SDK and no general HTTP client. It would be great if we could specify a property that it contains a hypermedia link and then the client provides an easy way to resolve such a link. I.e. we could add a new format hyperlink and if provided the value is not a simple string but instead a resolver class which uses the SDK to resolve the provided url. We also need to specify the schema which gets returned by the url.
