Yet Another Bingo

• Added smithing templates to the default tier lists, which I'd somehow forgotten in the last update
• Added more distinct item images for glass panes & waxed copper
• Fixed "cherry leaves" incorrectly being tinted green on the card
• Improved bingo map rendering performance (~20ms -> about 1ms per redraw)
• Attempts to improve bingo card color accuracy:
  • Maps have a limited color palette to work with, so I've been messing with the color similarity comparison being used to generate it. It's not perfect, but should look better than before.

If you're updating this on an existing server, you may need to delete the previous tier lists from ./config/bingo/ for these changes to take effect.
