Gas pump break chance

One of the problems I noticed with gas pumps is that while they provide an almost infinite supply of gas while filling up containers, they break almost instantly when filling up a vehicle directly. This rebalance raises the chance for pumps to break on filling a container and greatly lowers the chance of them breaking when filling a vehicle (it is now better to fill your vehicle at the pump directly then from a container for everything except steel jerrycans and aluminum kegs).

I also included a small typo fix that I stumbled upon (hydrogene tanks -> hydrogen tanks).
