New monsters

- Added new monster families: Bird, Beast, Cat, Elemental (Earth, Water, Wind, Fire)
- Elementals can be fused with any monster, but the result will be always from the elemental's element
- Added a new fusion filter that hides all combinations where both parents are from a different monster family

- Fixed performance during Fast Forward effect, also during rendering of the reserve in the Team menu
- Increased reserve members shown to 100
- Fixed game freezing when an event, like April Fools, is active
