[IDEA] Each entity with it's own data archive

[user-grinch]

Each entity will come with its own data .zip archive. The archive should contain below things,

1. Shadow textures for indicator lights, fog lights, rear lights, etc ( For vehicles )
2. Siren config file (preferably in JSON format) ( For vehicles )
3. Paintjob textures (future use)
4. The txd & dff file of the entity model

What does it solve?

• Installation will be drag and drop. No need for modloader. Just drop the .zip file inside ModelExtras/loader and it'll handle the rest
• Removes the clutter of spreading files across multiple locations.
