Job: Certain lua code for jobs.lua needed

We need a lua code / string for our jobs.lua with the following effect for certain jobs:

The player with this job will be targeted by friendly NPCs (like resistence NPCs) and hostile NPCs (like combine NPCs) will be friendly

Explaination: We want to create a PVP / PVE mode and in order to make this work, we need NPCs to recognize the players affiliation

We also accept alternate solutions if valid
