Bukkit

• Bane of Arthropods can now give Poison effects on all enemies. Default duration is 2 seconds per level
• Be a Ninja! Feather-Falling lets you sneak faster

• Dispensers can automatically equip armor when powered by redstone. As there is no way that I currently know to test for this without lots of redstone detection (which may cause lag), speed modifiers won't take effect for armor equipped this way until the player interacts (left or right clicks), or clicks a slot in their inventory. This should have minimal effect in combat, as the player is required to left or right click in order to fight.

Edit: Severe bug regarding knockback resistance not working properly and being active even when players have no armor on. Will fix in the future. For now use 1.1
