Custom coin images

[Potjeh]

New option when right clicking coins - examine. This pops up an image of the coin. By default a coin looks like a blank metal disc.

Add option to apply custom image to a coin press. Coins made with this press will show the image when examined. To keep coins looking like the metal they're made from, coin images should be converted to a greyscale overlay applied on top of the base coin texture. It should be possible to replace a custom image by applying a new one on the same press.

There are no practical benefits, but it's really sweet LARP-wise and I'm guessing it wouldn't take much work to implement. You could have various editions of your coin with different images, and if many people do this it'd provide a little minigame for collectors. The downside is obviously that the different editions of the same coin couldn't stack. Different editions should still count as the same coin when used in barter stands, though.

Would be nice if it could be put on the inventory object. Would make it easier to tell your coins apart, if you have multiple types, rather than hovering your mouse over each one.

Yes would be cool

Stacking problem could be solved by the press requiring the sketch when being built (and it wouldn't be possible to change it).
No editions then, though.

Nice would be if the press would mint the coins with a monotonic rising serial number (seen when inspecting) or there would be a way to query the absolute amount of coins of that brand in existance.
