Updated for AKI 3.2.1!

Updated to work with the new bot file layout from AKI and also updated the compatiblity version number (AKI 2.3.x).

Big thanks to Leppelin!

Fixed bot difficulty selection:

In the config, it stated the difficulty settings are "Easy", "Medium", "Hard", "Impossible" and "AsOnline". This was wrong.

The correct values are: "easy", "normal", "hard", "impossible" and "AsOnline".

This update fixes the comment in the config and the handling of the setting in the server.

Added configurability through config/config.js:

* Difficulty

* Scav/Raider to PMC conversion rate

* USEC/BEAR ratio

* Ratio of same faction being hostile

Updated SPT target version to match 2.2.1

Gave PMCs scav brains.

Should you find this too easy, try one of the previous versions in combination with Chomps easy PMC mod.

Replaced bosstest.json (BEAR class) and test.json (USEC class) difficulty files with the files named bear.json and usec.json.

In my tests, it seemed to work. No more total laserbeaming, not completely full auto to head/eyes, but bursting shots to the whole body.

Please report your findings, I really hope this works

Updated to include core difficulty settings and the bot presets from global config.

When updating, it's best to remove the old mod folder and install this version fresh (I changed the folder structure a little).

Playtested on Factory and feels much better.
