Upgrade to TypeScript 0.9.5 and support for single output file

L.S.,

This pull request includes the upgrade to TypeScript 0.9.5 and adds support for compiling into a single output file, along with a few minor other changes.

We would like to use the plugin with these changes to compile hawt.io TypeScript code.  Could you provide us with a release that includes these changes?

Thanks,

Gert
