Adding definitions to build output

Adding typescript definitions files to build output.  

I use the typescript services in my [atom-typescript-tools](https://github.com/park9140/atom-typescript-tools) and need the typescript definitions in order to write typescript correctly.  

Sorry, about the removal of trailing whitespace, you guys should really add some style checking to the project to eliminate this kind of issue.
i do not think you need this. only the services is the intresting one. there is no way to use the batch compiler from node as a package.
