• added custom signals for script refresh #10 by @hillyu
• added some cools example scripts #11 by @hillyu
• added single instance mode:

With the -si | --single_instance argument you may force single instance mode. The program on startup checks the pid file stored in /tmp/nwg-wrapper.pid and kills the appropriate process. You can use this only once, as always the same file is used.
