Potion Effects:
You're now able to add potion effects that stick to the player for a configured time on kit selection now! Also is made to where if you select another class your previous effects will be cleared, so users cannot stack effects.

Dyed Armour:
Dyed leather armor is now supported as a custom item type, so now you can have any RGB colored armor in a kit.

ItemDisplay Changes:
The ItemDisplay part of kits has been changed to use items like how the kits are setup, so now you can have specify more then just the material.

This update does require that you update your config, to do this rename your old config to something else then in-game do /ukitpvp reload to generate a new one. Then copy over any values that you wanted to keep then save and run /ukitpvp reload once more to get your old values in the game.
