Peaceful Progression

Makes blocks/items/dimensions available in Peaceful difficulty that normally require mob drops in vanilla by adding new ores, crops, mobs, structures, trades, and behaviors. This enables most progression to be completed in Peaceful, including getting an Elytra from the End islands and crafting beacons. Enables hunger in peaceful with no negative effects (purely cosmetic).

Adds new methods to acquire the following drops: Gunpowder, saddles, bones, blaze rods, breeze rods, ender pearls, froglights, slime balls, resin, phantom membranes, ghast tears, string, spider eyes, mob heads, prismarine shards, prismarine crystals, tide armor trim smithing template, nether stars, tridents, nautilus shells, wither roses, rotten flesh, trial keys, dragon egg/breath, ominous bottles, and more.
