ASP.NET Razor (cshtml) language support in Atom

Adds syntax highlighting and snippets to ASP.NET Razor (cshtml) files in Atom.

Originally converted from the Razor SublimeText syntax.

Assumes that the html (text.html.basic) and C# (source.cs) language files are already installed.

Contributions are greatly appreciated. Please fork this repository and open a pull request to add snippets, make grammar tweaks, etc.
