Made some changes to the MvcApplication class

- Renamed it to MvcRouteHandler
- Removed required IServiceProvider ctor param.
- The HttpContext flows the application services through to MVC. This does
 require a call to app.UseContainer in order for things to work but that should be fine.
 This will be the pattern we use for all frameworks going forward and we'll need to have some
 good error handling around this area when things aren't wired up properly.
