Implemented Splintery Chest in preparation for Magian trial work to come.
Corrected NPC model for Magian Moogles (they have different colored bobble/antenna thingies).
Split up the 3 Magian Moogles for easier scripting without future NPC ID issues or having to stand very close with pos checks.

Key Items attainable, but the actual magian trial stuff is not usable yet. Retail captures of the field on the item, as well as the parameter changes during event update would be greatly appreciated.
