Finish implementing alternate item textures

[object-Object]

From @walksanatora and @Talia-12 on Discord:

Although this is an enhancement, I'm prioritizing it higher than other new stuff because I feel like we should try to avoid releasing half-finished features if possible.

Current ideas:

• Just document the current pattern for cycling item variants
• Add a stonecutter-like block for this purpose
• Aly: "mixin amethyst bud's random tick to check for an item frame & transform the item it grows into"

Probably just document the pattern? That would be the easiest. I do think the pattern method is a bit janky but I'd rather not be blocking on a vanity decoration thing of all things.

Wow being in charge is great, I am pinged for my attention and I deign to give a response, and my underlings skitter around to do my bidding. I see why they hire interns
