Duplicate cmod/3ds models

[ajtribick]

We have several instances of duplicate models:

• amalthea.cmod / amalthea.3ds
• bacchus.cmod / bacchus.3ds
• castalia.cmod / castalia.3ds
• deimos.cmod / deimos.3ds
• epimetheus.cmod / epimetheus.3ds
• eros.cmod / eros.3ds
• gaspra.cmod / gaspra.3ds
• geographos.cmod / geographos.3ds
• golveka.cmod / golevka.3ds
• halley.cmod / halley.3ds
• hyperion.cmod / hyperion.3ds
• ida.cmod / ida.3ds
• janus.cmod / janus.3ds
• kleopatra.cmod / kleopatra.3ds
• ky26.cmod / ky26.3ds
• larissa.cmod / larissa.3ds
• pandora.cmod / pandora.3ds
• phobos.cmod / phobos.3ds
• phoebe.cmod / phoebe.3ds
• prometheus.cmod / prometheus.3ds
• proteus.cmod / proteus.3ds

In each case, the .cmod file is the one that is referenced by the catalog files.

While I can see that having the 3ds models around would make it easier to do editing work, I am not sure these files are necessarily wanted as part of an install target (or if they are, this should be made optional, e.g. by defining a separate component in the install rules and packaging it separately).

I therefore propose moving the .3ds files into a separate directory (e.g. "models-3ds") so that they can more easily be separated for installation purposes.

Imho it's better to keep them in models but exclude from INSTALL target.
