Issues #71 and #104

This will definitely provide a much improved debugging experience. I'll work on updating the docs tomorrow.

In case you want to try debugging out you should:
1. Open VS.
2. Open Existing project -> scriptcs.exe
3. Right-click to pass args.
4. Add files to debug to solution (add existing items).
5. You should be able to add breakpoints anywhere, run the app etc.

Regarding the code, let me know if you would like me to make any updates.
