[System.Web] ASP.Net MVC5 missing methods fixed

I have added System.HttpApplication.RegisterModule(), the missing two properties of the System.Web.Routing.RouteCollection as well as the corresponding property in the HttpRuntimeSection to completely turn this off. Microsofts MIT-Licensed counterparts of the official System.Web assembly from github [0] were used as a reference. It is kind-of bolted on, but should be good enough until the whole open-sourced System.Web is incorporated. It should at least get the default MVC5 Template from Visual Studio 2013 up and running, once the async pipeline for the owin stuff is fixed.

[0]: http://github.com/Microsoft/referencesource/

Additionally, the MissingMethodException "get_InClientBuildManager" in System.Web.Hosting.HostingEnvironment was fixed.
In this commit, the following bugs were fixed:
