Dumpster

Fully rigged dumpster, based on [this version by YJ_](https://sketchfab.com/3d-models/dumpster-989ea7f01b924859b3484ee27103e8d9) * Mesh cleaned and simplified, many overlaps and holes filled * Interior and underside of lids now have surfaces * Two lids rigged to different bones allowing opening separately * Faces assigned to different materials for wheels, frame, and lids * Wheels now attached to frame instead of floating in mid air ;) There's still quite a few minor problems with this mesh such as backfaces visible in small areas, but unless using in an extremely close view, they are not apparent. UV maps NOT updated, no textures included (the intent is to use a single color shade for the various materials).
