Improved block item dropping, this enables enchantments and spells to work better and more effective. (This might affect other plugins that are using custom block drops, if you find an issues please report it)

Added experimental enchantment and spell priorities. You can define priority for enchantment and spells that affects the order of their execution, the higher the priority, the later it will be executed. No priority or 0 will be ran first. Note, that priority does not work for inherited enchantments.
Example in enchantments.yml file:
This will make enchantment critical be run after all 0 priority enchantments.

Fixed spell usage not taken having multiple spells on an item.
