Gives syntax highlighting, validation and Intellisense for .editorconfig files
This is meant as a pull request to https://github.com/editorconfig/editorconfig-visualstudio
I can't compile your project, since I don't have VS 2010 installed.
This code should be Visual Studio 2010+ compatible though. All you have to do
is to copy over the file EditorConfigTextViewCreationListener.cs and the folders Classify, Completion, validation and ContentType to
the .editorconfig VS extension project and then add the missing references.
Sorry for such a lame pull request
