check for avatar skeleton data on meshs headers on cost estimation. Dont

 let a model have more than one mesh with skeleton, for testing create a
 mesh inventory item, for this meshs. Add also option to read a avatar
 collider replacement. This information still needs to be saved somewhere
 so it can be checked on attachment, etc, without parsing the mesh asset again.
