Add Visual Studio Support for this project

It would be great if I could replace my Compass -watch workflow for something mostly out of the box or at least built in to the existing extensibility model.

I'd recommend Mindscape for this use; you have to buy Pro for LESS compile support, but it's definitely useful.

I'm not going to do this, but I'd happily accept a pull request if someone is interested!
