- move `DynamicObject` derivation up to new `DynamicViewData` class, fixing [WebFx-169](http://projectk-tc:8080/browse/WEBFX-169)
- avoid direct `_data` lookup in previous `TryGetMember()`, fixing [#118](https://github.com/aspnet/WebFx/issues/118)
- rename ViewData -> ViewDataDictionary
Also
- flesh out `IDictionary<string, object>` implementation in `ViewData`
- provide `ViewData` copy constructor that allows TModel to change
- remove `TryGetIndex()` and `TrySetIndex()` implementations; use `ViewData[]` instead
- restore `ViewContext.ViewBag` from legacy MVC
- use Microsoft.AspNet.Mvc.Rendering namespace throughout assembly
Also
- move `IdAttributeDotReplacement` from `TagBuilder` to `HtmlHelper`
- remove commented-out code in `HtmlHelper`
- use `var` and `[NotNull]` more
- `String` -> `string`
- correct Resources references; add missing resources
