- includes new `RazorPage<TModel>.CreateModelExpression<TValue>()` method
- #1240
nit:
- regenerating the resources reordered Microsoft.AspNet.Mvc.Core's Resources.designer.cs
* Introducing RazorPage and RazorPageOfT that represent the Razor
execution aspect of view execution. Moving view execution hierarchy behavior
(Layout, partial views etc) into a separate RazorView type.
* Renaming IVirtualPathViewFactory to IRazorPageFactory,
IRazorViewActivator to IRazorPageActivator
* Renaming VirtualPathViewFactor to FileBasedPageFactory to
correctly reflect what it does.
Fixes#814
