MrFancyPants Equipment Manager

- Changed save data format, this WILL WIPE ALL OF YOUR SAVE DATA

- The new item format should be significantly more robust and should catch more 'differences' between items

- The new item format makes dropping in the EquipItem API significantly easier when the time comes, so once Carbine is ready to release it to us - MrFancyPants should be ready to use it!

- The addon should no longer show you equipment to equip if that slot is already 'satisfied' (so you shouldn't get stuck in duplicate item loops anymore)

- You can now make 'partial' sets that will ignore certain slots
