Streamlining the exchange of models that use unofficial parts

[Orion Pobursky]

This has really only became a problem as the major viewers/editors started added support for reading the Unofficial directory and then only if a user has consciously installed the unofficial parts package. This mean that a model author knows what he/she is getting into and should know to distribute the model appropriately. In my case, I simple overlooked it. My point is that I think leave things the way they are is best. Otherwise we risk "officializing" the unoffical parts.
