Forager Bow Enchantment

Adds a new Bow enchantment, "Forager", which teleports items/xp.

"Forager" is a new Ender-themed Bow enchantment which can only be found in End City Chests. This new enchantment has two levels (I & II). The first level teleports XP Orbs upon killing an entity with the enchanted Bow. The second level teleports both XP Orbs and Items upon kills. The Forager enchantment is related to the Enderman's power of teleportation - as is indicated by the purple particles and teleport sound when XP/Items are teleported, as well as where its found.

A few notes:

• The "Forager" effect works as normal with all Arrow types, including Spectral and Tipped Arrows.
• The "Forager" effect will not occur if you use a "Forager" enchanted Bow with Tipped Arrows of Instant Damage, Poison, etc and the potion effect kills the entity.
• If you're playing with my other mod "Arrow Entity Loot Drop" installed, the dropped arrows will also be teleported to you.
• With Cloth Config installed, you can use the mod's config to control how the "Forager" enchantment is obtained & control whether "Forager I" does XP or items only.
• At some point I'd like to add support for Crossbows, but EnchantmentTargets make that tough.
