Adds bunnyhopping, strafe jumping, air control, trimping, and sharking to Minecraft and removes losing speed from taking fall damage (needs to be installed server-side for this). Bunnyhopping is uncapped by default, but has config settings for Fortress Forever-style soft and hard bunnyhop caps. The air and ground acceleration code is actually based on Half-Life, but it should be fairly similar to Quake's. The trimp mechanic is a modified version of the Fortress Forever trimp mechanic: if you're moving fast enough, holding sneak while jumping will convert some of your horizontal speed into vertical speed. Sharking refers to gliding across the surface of water by holding jump.
