Support for inline source maps

[velara3]

In Typescript you have an option to put source maps inline in the exported js output. This is useful when you have a lot of files in the project. Basically, including source maps doubles number of files.

Example:

/project
   - MyApp.as
   - DataModel.as
   - /bin/js-debug/
      - MyApp.js
      - MyApp.js.map
      - DataModel.js
      - DataModel.js.map
