Removed Defibs and First Aid Kits in Realism Versus. Survivors start with a First Aid Kit, but all world spawns are disabled.
Addons
To avoid conflicts between Community Campaigns, only content vpks get loaded when starting a campaign.
Added console command "show_addon_load_order" that prints out the order of loaded vpk files.
