Spawner storage leaps to 250 million, and natural spawners need a Spawner Wrench

• Spawner storage is now far larger, with two new levels above the old cap: 100,000 / 500,000 / 2,000,000 / 10,000,000 / 50,000,000 / 250,000,000 items. Every spawner you already own is raised to the new capacity for the level you bought, at no cost, so there is nothing to rebuy.
• Naturally generated spawners on Lifesteal now require a Spawner Wrench to pick up. Spawners you placed yourself still come back the way they always did.
• Spawner loot on Lifesteal now lands as full stacks, and nearby identical drops merge into them, so farms create far fewer item entities. In practice, that means fewer loose drops left lying around your farm.

The two new storage levels sit alongside the existing ones as storage upgrades for your spawner. Raising an existing spawner's buffer leaves its stored items, its other upgrades and your money untouched.
