Final Modfest Release (hopefully)

• Fixes several lang keys. Tipped arrows and lingering potions now display their names and effects correctly.
• Fixed a problem where Arrow of Mutagen wouldn't mutate animals it didn't kill
• Despawn timer added for mutants that have been left idle (unridden)
• Config added, for now it only configures the despawn timer

Initial release

• Adds Mutagen and Splash Mutagen potions, brewable as if you were trying to make a Thick Potion of Poison
• Salmon turn into a huge, rideable mutated version when hit with Mutagen
