Scene Manager: named LODs

{lod} in SCENE_MANAGER_LOD_COLLECTION now matches any name (COL_bob_LODhigh
as well as COL_bob_LOD0). SCENE_MANAGER_LODS (high, mid, low) sets the
button order and the LOD shown on load; unlisted LODs follow, numbers in
order, then names A-Z. It replaces SCENE_MANAGER_DEFAULT_LOD. The LOD of
Selected buttons get their own line.
