Added ModelEngine support. Models must be put in the ModelEngine\blueprints folder. My plugin just uses the engine and it's opportunities.
At the moment, you can set models for two screamers: Weeping Angel and Crazy Guy. P.S. I'm bad at modeling, so I'll leave it up to you to create models with their animations.
Now you can nicely customize the Crazy Guy screamer by modifying it's spawn distance, sounds and movement speed. Make your own super scary screamer flying into the player!
