Pots should be able to be dyed, and shards should be trimmable

This would allow for greater variety and expression in the pots that we can construct. I don't know if pots should have the same dyeing mechanics as leather armor, as I don't know how simple or complex the code is, but that would be a boost to variation. Being able to apply colors to the pot shards before combining them into the pot would serve the same purpose.
