- copy over from legacy MVC
- fixup namespaces, remove copyright notices, ...
- temporarily remove `RouteBeginForm() overloads
- move main components to `HtmlHelper` and declare in `IHtmlHelper<T>`
- change `UrlHelper` to avoid treating an existing dictionary as an object
- add `HtmlHelper.Createform()` factory
- use in MVC sample; move BeginForm / TextBox samples to a new row
We'll create a scoped service provider if the middleware that does it
isn't there.
We resolve all of our stuff from the scoped service provider, allowing
users to plug in any scoped things they want.
Ported UrlHelper to be a scoped service.
- 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
