Store full skeleton path

Skeleton loader saves file paths now:
C:\...\Objects.ocd\Items.ocd\Tools.ocd\PowderKeg.ocd\PowderKeg.skeleton
C:\...\Objects.ocd\Items.ocd\Tools.ocd\Shovel.ocd\Shovel.skeleton

The sickle is still not loading, because the engine requests "sickle.skeleton" and the file name is "Sickle.skeleton"
