python - rc: Add initial SIGINT handling and correction PL creation.

Log Message:
-----------
Add initial SIGINT handling and correction PL creation.

- Add recreate_proc option and stop dropping the procedure by default.
- Fix PL creation. It was simply broken.
- Make three consecutive SIGINTs act as a local interrupt.(1 second window)
- Use new GreenTrunk location.
- Fix version display. It actually takes -V now. :)
- Add support for -m and -c options.
