Logistics

This is currently still WIP, it builds off of this discussion: https://github.com/KoffeinFlummi/AGM/issues/48

I am doing this pull request now, just to see what thoughts or ideas can be added to this or perhaps this direction is not something that is desired for this project at the moment. However, I think it is a good idea to consider it and its merits.

Pros:
- A nicer visual appearance for players
- Handles how to store the object when it is loaded

Cons:
- Has to be set up in config for each vehicle that can support it (however, it could fall back to the "magic menu" functionality if not configured for it)
