Persistence update

WIP - using assignedItems to more accurately track what a player has on
them. Now possibly revert back to using backpackItems and vestItems.
More work on player persistence
Merge remote-tracking branch 'origin/Development_main' into PlayerPersistence

Conflicts:
	config.sqf
Lots more persistence work
Player persistence seems stable now
Remove setup.sqf and A2NET legacy cruft
Final commit before pushing player persistence
Merge pull request #40 from A3Wasteland/PlayerPersistence
