Double Jump Boost

Replaces the increased jump height from jump boost with a double (or triple) jump, based on the effect level. Each level of jump boost allows you to jump one more time in midair. Landing will reset your jump count, and a successful mace hit will recover one jump. As you'd expect, jumping at the end of a fall before hitting the ground will avoid or reduce fall damage depending on timing. This makes jump boost more controllable and desirable in survival mode.

This idea came from an episode of The Spawn Chunks podcast.
