Support for inline source maps

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
```
