Modular vehicle [WIP]

What’s new today:
Modular vehicle class hierarchy improvements
Wheels SFX
Simple Day/Night cycle
Ability to enter/exit vehicle

Anti-stuck measures:
Savepoint every minute
Manual respawn to the last savepoint
Auto-respawn on stuck to the last savepoint
As a last resort, I’ve added jumpers as an anti-stuck device.
