Update to use typescript.api for 0.9.1 compiler support.

Hey Josh,

This fork uses typescript.api instead of your hand rolled compiler class to update your brunch plugin so it can compile typescript files using the latest version of the typescript module. Node projects that use it have to include lib.d.ts in their own source if they want to access the DOM (this is the way typescript.api works). I have tested this locally and it compiles fine but I would like you to review it and give me some feedback. I can fork and update your todos project if that helps as well.

Thanks for this plugin!

Jayme
