Place lobby particle entries relative to the body

Entries get a World/Body setting. In body mode offsets, heights and wings
follow the body's facing and lie along the body while gliding or swimming,
so wings stay on the back. Rings circle the body but keep their world
angle, so they do not turn with the player. New wings default to body;
presets and rewards stay in world mode and look exactly as before.
