1. During the conversion of Morphia calls to the new API, some of the `Filter.eq()` calls had their `field` set to `playerId` due to a copy/paste typo.

Out of my madness and suffering I have achieved the impossible. I almost lost all hope and was about to end it all. However, it worked out in the end and now we have gacha reloading.

sorry again, forgot to add

Additonal stuff: Fixed + refactored help command. Removed 'Usage: ' from all commands. Created 'player.hasPermission(permission)' function. Created default for Usage annotation. Created hashmap version of 'getHandlers' and renamed the original to getHandlersAsList()

Fix issue with a player not being able to spawn when they join somone in co-op with a singleplayer team of more than the max allowed amount
