When collecting Jobs from the server it tries it's best to determine which role is the "Boss"
It checks first of the Job Grade label containing the word "Boss"
If it can't find it, it then uses the highest number grade and adds `.isBoss = true` to it
Added a check to the script start to get the current players duty (helpful if yours saves the duty through restarts)
Also added core specific triggers for job/duty changes to help keep these in sync
Nothing public uses this yet, but its very similar to QBCore which makes it very for me to support
Nothing special to note, just improves the integration for future ventures into RedM
