Car crashes generate items

[Faustie]

There is now a chance that a car crashing will generate and spawn a couple of crafting items, RP-wise damaged car parts. The chances differ for each of the three items (scrap metal, scrap electronics, and spare parts), with scrap metal being the most abundant. This provides the first of many methods for players to get these crafting resources passively, rather than only through theft. Obviously, some people may minge and crash their cars multiple times, but then you have to pay for repairs, too. If it gets too bad I'll make it so no car can generate any items more than once per hour, but hopefully that won't be necessary. Let me know your thoughts on this.
