Disable logging of commands that dont exist

[Scorpio622]

Describe what you want to be implemented
Disable logging of commands that dont exist, basically the ones that state at the end "Result: 'Command not found.'"

Motivate why this change is needed/appreciated by the community
People play on multiple different servers, and since servers have different commands/plugins, they usually will try to use them and flood the commands logging event. Its just logging spam, since the command doesnt even exist, that information doesnt benefit anyone.

I will not implement this as I think this type of logging fills a purpose both for security when players are trying to find exploits and also for seeing what user expect to be able to do on the server.
