Docs: [Project] Add the Roslyn API reference to docs

[BillWagner]

The Roslyn APIs (aka the .NET Compiler Platform SDK) should be on docs.

See this project for sub-tasks.

Somehow, I'm not surprised @svick wrote this some time ago.

The Roslyn APIs are now live on docs.

Thanks @dend and @meganbradley

Awesome! Next step: fill out documentation for the many members that don't have it from XML comments. 😄

Also, I can't find documentation for the Microsoft.CodeAnalysis.ISymbol interface. In fact, the whole Microsoft.CodeAnalysis namespace looks suspiciously empty. It seems the only type there is from the Microsoft.CodeAnalysis.CSharp assembly, but all types from the Microsoft.CodeAnalysis assembly are missing (at least for that namespace)
