[feature request] Accept changes of cnc_tips.txt without restart of the program #34

After change a cnc_tips.txt file, I must restart program to allow usage of new changes.
If file is changed just little bit, then this restart is not a problem.
If file is changed very often (I write tooltip to new undocumented CNC, so I put changes in the file by little portions in different places of the file), then restart program is delays me up to 50% of work time.

Please, add procedure, which monitor changes of cnc_tips.txt files (minimum are: program path .config/gcodeworkshop/, and current project path .config/gcodeworkshop/), then reload new version of the file, reset old tooltip configuration and apply new version of tooltips configuration.
