Turnaround Camera: Cleanup, UI changes
Bumped version to 0.2.5 Imports as tuples Consistent property definitions Use a property group for the scene props Access through context.scene.turn_camera Reorder the UI layout Added the option to clear the camera animations as the previous run can leave the Dolly Zoom active
