* Fix bug: if mods changed and previously selected faction no longer exists, would crash the mission
* Fixed a bug that could slow down the server significantly in long games

Fix missing civilians in faction optimization update.

Optimize faction selection code: If you had a lot of factions (like when using RHS) it could take around 20 seconds to load the factions. It now takes less than 3 seconds and runs during mission start so the faction selection UI should be much quicker too.

* Add ai teammate 'previous' loadout option
* Improve when AI teammates revive:
+ AI will only revive if they are not stopped, all players are down, or they are within 10m.
+ AI that were stopped will return to their previous position after reviving
* Fix bug when arsenal was in 'faction' mode it was empty.

Another fix to work with mods that have faction side as a string instead of a number.

Fix for mods whose config for faction side is incorrect.

Fix bug in enemy count

Added an option to set the AO size to 'normal' or 'large'. 'Large' will set the AO (Area of Operations) 50% larger without increasing the number of enemy. This helps the enemy spread out a bit more. If the number of enemy still seems a bit too much for the area, try reducing the enemy count from the default 'Autoscale 3x' to 'Autoscale 2x' or 1x as that will spawn less enemy into the zone.
