Edited Issue: Injecting custom IActionResultConverter implementations through the DependencyResolver as a service or based on rules [551]

@kichalla and I have discussed this issue also on http://aspnetwebstack.codeplex.com/discussions/399311. Today, you need to jump a lot of hoops to provide a custom IActionResultConverter implementation because the HttpActionDescriptor has a deep knowladge about the ActionResultConverters (see the virtual ResultConverter property of HttpActionDescriptor).<br /><br />It would open up lots of flexibilities if custom IActionResultConverter implementations can be injected through the DI as a service or based on rules (just like as it is with HttpParamaterBindings today).
