Add UAV Hacking by giving players UAV hacking trait

[StormCircuit]

Can I just edit the mission file and upload it as a new version for a PR? Or would that cause problems, I figure you might have edits you need to make and we may overwrite each other.

The mission file change might not work properly with respawns. I am not sure if the trait would carry over when respawning, so what I am going to do instead is add the trait in fn_setupPlayer.sqf so respawns aren't an issue.
