[Updated] Smaller pocket tanks, Air Vending Machines!

[Sundance]

I like this idea, I may try to work on it.

I would definitely like the idea more if there was something like this.

I think Pay-4-Air is a far better system than draining the already questionably full oxygen canisters to fill a tank (that interface is kind of janky imo).

Hmu if your interested in some sprites. I'd say it would look very similar to a vending machine.
