E-Wallet object added.
Made ATM to spawn e-wallets.

Untested.
-Ewallet can be extracted and inserted from and into ATMs.
-Working with EFTPOS.

Todos:
-Vending machines.
-Proper icon.
-Proper name.
-Test.
First commit for review:

-ATMs no longer spawn spacecash when you Withdraw funds from them. Instead they spawn a charge card with the funds asked.
-You can swipe a charge card at an EFTPOS instead of your ID. The funds will be substracted from the charge card and won't ask for any PIN.
(ID card swiping is still available, of course)
-You can insert a change card in a vending machine. You can retrieve multiple products from the machine as long as the change card has enough funds to pay for them.

-Also, the EFTPOS instructions are rewritten into a simpler text. The text is not final.

Needed:
-A better name than "change card"? Also, until a name is set, variables are keeping the name "ewallet".
-An icon for the change card. For now it's using the 1000$ cash icon as placeholder.

Fueltanks leak fuel when wrenched open

Fueltanks now actually leak fuel when wrenched open. The leaking only occurs at the initial wrenching and when tank is moved.
Adjusted fuel spread

Made fuel stickier, so it spreads less thinly.
