feat: Dragonmaw (#1562)
* rigid as heck

* abstract physics creation to separate function

* loading

Update FvRacePillarDServer.cpp

consolidate abcd pillar logic

modularization

Update SimplePhysicsComponent.cpp

Update EntityManager.cpp

Update MovingPlatformComponent.cpp

still need another pass

* geiser works

* columns working finally

* consolidate logic

* constiness

* Update PhantomPhysicsComponent.cpp

* Update PhysicsComponent.cpp

* revert testing code

* add versions info
