Subject: coment out mesh model upload code to add textures and individual
meshs assets to inventory, since it may actually be a bad ideia since good
model textures are deply related to it and there is no current use for
independent mesh assets. Added the option to have a reduced free for textures
(2.5 C$ as is, total textures cost rounded to nearest int) compensating for
the fact that they can't be used outside the model or its parts.
