Subject: blinkled.inc - style fixes and code rework

- Add copyright headers
- Code style fixes
- use is_process_running() instead of blinkled_running ()
- remove blinkled_stop() and blinkled_start in favour of start_service()/stop_service() in order to actually utilize the service in a meaningful way
