Currently there is no way to tell if a script has been added to the script scheduler, and only diag_activeSQFScripts in a loop can somewhat detect changes.

This implementation of script scanning isn't very efficient, so I propose to add a missionEventHandler for when a script is added to the scheduler via 'spawn'.

This even would ideally have the same and/or have more info on the executed script than diag_activeSQFScripts, and would mainly be used for security and/or debugging script heavy systems.

Ex.

scriptName: String - Returns:
    Script name set with scriptName - May not be possible obviously, depending on how and when scriptName is set
    File name if script name is empty
    Preferably the entire executed script to run regex checking
filePath: String - path of the parent script

Would be nice to also return whether or not it runs, but I am not expecting it to be possible/worth the time it would take to add.
