Familiers – Pet Manager

## 1.3.0
- Ownership transfer: pick a nearby player (120 blocks), they accept or decline in chat
- The pet is stored automatically and moves to the new owner's list; the old owner loses all access
- Owner is changed in-game too (vanilla, horses, Ice and Fire, Aether Moas)

## 1.2.1
- Removed the "Forget" button
