Edited Feature: Support "Ignore Route" in Web API or remove dependency on MVC [762]

I have a Web API only project with no dependency on System.Web.Mvc.

So that I can use Elmah I need to add an ignore route like below:

routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

Since ignore route is included in System.Web.Mvc rather than System.Web.Routing I have to add a reference, or internalize this extension (which is what I've done).
