Revert "Fix plugins adding recipes violating sorting contract. Closes #238."

This reverts commit 5f8283f04060ba9771d0374cae062466e934ca58.
Complete fix for plugins adding recipes violating sorting contracts. Closes #238.

Disable recipe sorting in Bukkit addRecipe(), fixing any issues with
sorting modded recipes. Sorting still takes place after the vanilla
recipes are initialized, as usual.

Vanilla and Forge do not sort when new recipes are added, so this
change matches their behavior. Plugins depending on the order of
recipes with respect to shaped/shapeless may be impacted.
