Hotfix for overrides with RavenCreekPD Support.

Content Update (for once!)
* Added zombie outfits that should only appear when the mod "Susceptible Trait" is added.
* Fixed the key auto-renaming feature of Overrides that broke when I refactored it to only rename under certain circumstances (you can now rename your keys without them reverting)
EDIT:
* Forgot to mention I put in an experimental, less laggy method for running Overrides. From my limited testing, there was at least a 15% increase to FPS

Another save breaking overhaul. This one's beneficial, I swear!
* Added USPS and Judge content.
* Moved most of the old loading system to sandbox options. Only stuff remaining can't be transferred over to my knowledge.
* Minor fixes, like SmallTownOverrides not affecting Meade County Sheriff content. STO is STILL buggy on servers!!!

New features:
* Added JeffersonCounty EMS Uniforms and Ambulances
* Added Firetrucks
* Some minor bugfixes.
Do note that I wanted to get this out there, aas we already passed the promised deadline. So Vanilla vehicles aren't supported. For now...

Welp. Due to the plug-n-play update literally being an utter mess on servers. I am reluctantly reverting the changes.
I'm sorry fellas, I'll make it up to ya'll. I promise...

Actually fixed the spawning and locker code breaking when one spawns in a police station. Twas (HOPEFULLY!!!) an easy fix, luckily...

Whoopsie fixeroono.

Moved the old system to the legacy branch.

MASSIVE code cleanups. Code's a LOT more readable now.
Revamped the spawn code to be more plug-n-play. So now you don't need map files!

Minor code cleanup.
Added some compats for Shark's law enforcement mod.
