Tactical Retreat

When shot, enemies don't die but instead just go home.

Changes matchmaking key.

Known issues

• Sometimes enemies just disappear

It means they couldn't find a path to leave the level. There really are only 2 options what can we do if we can't way out: die or disappear.

• Kills aren't counted
• No "special is killed" lines
• Not all "on kill" skills are triggered

These 3 are just annoying to fix because all the "on kill" effects are all coded differently for no good reason

• Stealth is trivially easy

Stealth could be made harder in the future, but right now you really have to go out of your way to make guard activate a pager

• AI gets traded out of custody randomly

That's just due to how the whole going home mechanic works - we technically just trade them. Ideally we would an entire separate logic to handle leaving after getting shot, but it would be a pain to implement.
