Avoid duplicating skeletons due to casing issues

Manually created resource names are apparently always case sensitive, causing
some skeletons to get loaded multiple times.
Share the space with the parent entity only when there's real skinned meshes

The existence of a base skeleton doesn't mean it shares the same bone
structure. If there isn't an actual skinned entity besides the base, simply
attach it to the bone like unskinned meshes should be.
