Enchant the Rainbow 1.0.1

When you equip items with custom enchantment glints into Trinket slots, e.g. from a mod Vanity Slots or Cosmetic Armor, items show their default enchantment glint colour instead of the correct one.

Let me know if logs are necessary.

And on a side note, I'm using armor from DragonLoot and the enchantment glint works strangely with its winged chestplate. When you apply a custom glint to it, the chestplate uses the new colour, but not the wings, even though it's a part of the chestplate. Is it something that you could look into?

Thanks for reporting! This is probably something I have to build a specific Trinkets injector for. I'll add it to the to-do list.
