- Moved source models related classes and implementation into separate files.
- Created a new UObject wrapper for holding mesh description bulk data; this is created as a transactable object inside a UStaticMesh.
- The cached mesh description is now an inner object of the bulk data wrapper; this allows transactions on the bulk data to affect the cached mesh.
- The static mesh SourceModels array can no longer be accessed directly: FStaticMeshSourceModel requires extra initialization before it should be used, so new LODs should be added through the static mesh API.
- Undo/redo is now fixed within the geometry tools
- Fixed regression where mesh description was being unpacked unnecessarily during transactions
- MeshDescription bulk data and its cached MeshDescriptions are now emptied prior to removing the UObject reference, in order to immediately free memory instead of needing to wait for garbage collection
- No more deadlocks when clearing or committing mesh descriptions during garbage collection
- Bulk data UObjects are constructed, where possible, at startup, in order to prevent it from happening during critical moments, e.g. during garbage collection or package saving.

Toolbar grid toggle button now syncs with viewport grid states. If any viewport is showing a grid, the toggle will be on.
