Add a remove item mechanic to MythicMobs

Summary

Mechanic that removes x amount of an item from a player's inventory.

Usage

Can be used with a mechanic using onInteract with an holding item condition so the item is consumed. At the moment on the manual there a RemoveHeldItem mechanic BUT it is listed as artifacts only.

Value

Good mechanic that adds interaction possibilities to mobs.

Priority

Medium high, I think this would be really useful for some people.

Implementation

Mechanic that asks for type of item and amount, then removes that from target player inventory.
