Add fuel siphoning to the game.

You can now siphon fuel from the vehicle examination screen. Requires a hose.

Eventually I'd like to add a Mechanics recipe to make an alternate siphon item out of pipe or something, because hoses are really too rare to be the sole item for something as important as fuel siphoning.
Siphoning is possible on any tile of the vehicle now
Make siphoning take the same time as refueling
Make hoses usable (as a tool) to siphon gas
