• Updated IsaacSaveManager to current latest version v2.2

Updated MIT License file to reflect new online handle

• Fixed issue with errors being thrown if you didn't have REPENTOGON
  
• Added parameter "LinkedUniqueObject" when using AssignUniqueObject. Specify ObjectID and ObjectType. If that ID and type exists under the same currently registered mod for the provided PlayerType, it'll automatically be active. Does not show inside ModConfigMenu
  
• Added ObjectType.EFFECT. Works as expected for EntityEffects
  
• Callbacks for Familiars (as well as Effects) are now only active for the variants registered under the API instead of running for every familiar
  
• Fixed a bug where changing a Unique Collectible's setting to Disabled will have it show Sad Onion

• Updated to latest save manager version. Should fix any obscure errors.

• Code has received a complete rewrite
  
• All API functions that were separated by Items, Familiars, and Knives have been merged into one
  
• Previous API functions are still available and still function for backwards compatibility

• When registering a character, you can now specify a "DisplayName" as the third argument to display a name different from their players.xml name when viewed in Mod Config Menu
  
• All Tainted characters will automatically have "Tainted" prefixed on their name if no display name is provided
  
• It is no longer required to register an item, as it is done automatically via "AssignUniqueObject". In its place, you can call "AssignObjectName" to change its displayed name in Mod Config Menu
  
• Save data has been replaced with IsaacSaveManager and actually works this time. Old save data will not carry over.
