Test for XML documentation errors
- extend the "test" target in our build to use new k-xml-docs-test.shade command

Example output with one syntax error and one invalid reference:
```
info: Target xml-docs-test
warn: Invalid documentation syntax in src\Microsoft.AspNet.Mvc.Core\bin\debug\net45\Microsoft.AspNet.Mvc.Core.xml
warn:   3170: <!-- Badly formed XML comment ignored for member "T:Microsoft.AspNet.Mvc.Rendering.HtmlHelper" -->

Improve XML comments in `HtmlHelper` and related classes and interfaces
- #847 line 1: copy XML comments from interfaces to extension methods
- lots of wording changes to be more consistent
 - core text split from PR #866, where @rynowak and I hashed out the words
 - to extent possible, reuse words between method descriptions

- add a few missing `<param/>` and `<typeparam/>` elements and fill in empty ones
- display more HTML elements as tags
- use `<c>true|false|null</c>` more often
- add `<remarks/>` describing behaviour of input helpers e.g. `CheckBox()`
- add `<remarks/>` explaining "renders"
- add `<remarks/>` containing example expression names

nits:
- "The expression" -> "An expression"
- make examples for `ObjectToDictionary()` and `AnonymousObjectToHtmlAttributes()` more consistent
- move `<typeparam/>` elements (that existed) after all `<param/>` elements
- explain "checked" attributes better, removing some duplicated words from the `RadioButton[For]()` descriptions
- correct `routeValues` description in `GenerateForm()` comments
ViewEngine shouldn't throw when it doesn't know about the extension
