Mythbound Magic

- Redesigned the soulstone mount system. I found out that registered entities can come in conflict because it is a generic name, not domain/name. That being said it was only a matter of time before my creatures caused problems with other mods using the same name. This is now fixed.
- Added the following soulstone mounts: Antelope, Grizzly bear, Polar bear, Doe, Stag, Snow leopard, Mosshorn, Ram, Sheep, Sabertooth tiger, Black wolf, White wolf, Scorpion, Spider, Cave spider, Crab, Crocodile, Lobster, Earth crystal golem, Flame crystal golem, Frost crystal golem, Sand crystal golem, Thunder crystal golem. 
- Changed the soulstone use cooldown to 1s, down from 10s.
- The spell selection gui no longer closes when you select a spell.
- Migrated my code off of using the depreciated player.GetPlayerRef! We are learning!
- Created a new creative tab for all mod objects.
- Enhanced the spell system to support particles and sounds on completion. Now I just have to make them...

Next update I will be focusing on how spells will actually work now that the proof of concept is working well.
