cleanup Responder::display for @goldstar.
adding a response test for Content-Type and the likes.
cleanup test_helper and require test_xml.
render models in our responder and pass back a Responder::Response object, which is then handled in Controller#render_to_body. makes it super simple to add new formats like :hal without having to extend the controller etc.
extend HAL with to_/from_hal.
remove representable as it is required by roar.
added help text for "Rendering Options" to illustrate how a representer
makes use of an option that is passed to it.
some README tweaks ;)
