Potions and Stuff

Made 6 new potions (with functioning arrow recipes on the fletching table). -Wither (made wit wither roses): self-explainatory. -Displacement (made with chorus fruit): makes you teleport around. -Thorns (made with cacti): self-explainatory. -Vampirism (made with suspicious stew): self-explainatory. -Health boost (made with enchanted golden apples): self-explainatory. -Resistance (made with scute): self-explainatory.

And a new secret one (currently unobtainable by normal means): -Transmutation (made with a command block): makes mobs easier to deal with, and makes fun changes to the players.

Some strings in the lang file might be missing. I'll release a hotfix tomorrow.
