FZero Drops

Please, run /function purpura:load.

I'm pretty sure that Sigils and Vinculum Maggia from previous experiments no longer work in this version; I changed the way to handle custom data.

It still partially dependent on a verion of FZero Drops.

• Added 3 sigils:
  • Sigil of Bonanza: doubles up to 3 potion entities in a full water cauldron.
  • Sigil of Echo: turns the Vinculum Maggia into Echo Vinculum Maggia.
    • Echo Vinculum Maggia increase the number of splash potions in your hand when you kill a hostile mob with magic.
  • Sigil of Pyrius: turns 1 charcoal entity into gunpowder.
• Adjusted a lot of minor details that I really do not want to write.
