[Feature] Loot Crates

[Frankity]

New traitor item, akin to the surplus crate. It will give you a guaranteed 10x pharosium bars, 10x mauxite bars, 10x molitz bars.
Then will select between 12 and 36 random things including materials (various ores like cerenkite, syreline, etc), bitcoins, credits, and the easter eggs.

Useful for the more sophisticated traitor who wants to build a deadly contraption, or a sweet custom pod, or even just some erebite saxaphones. 

I am quite bad at computers so I probably did all of this wrong.

For some reason my end the loot crate isn't spawning anything. I'll have to come back to this later, something might have changed our end.
