Export ts to CommonJS

This is for #372

Exports the `ts` module from the language service so people can do `require('typescript')`. 

Notes: 
- To run the test put `runners.push(new UnitTestRunner(UnittestTestType.LanguageService));` in `runner.ts` and in `nodeExport.ts` use `it.only` and then `jake runtests`. 
- I forgot my CLA in the office on Friday. Will scan and send on Monday so this PR can wait till then. Will message once its sent.
