Investigate if sub faction unit and building variants should have model variants

[xezon]

Investigate if sub faction unit and building variants should have model variants. By default, all Workers, Dozers and faction buildings, apart from the Command Center, look the same. Differentiating the models could help readability when controlling multiple factions. However, this also allows to read opponent faction in Random match-up much quicker.

Shockwave Mod already does this for Workers and Dozers, but not for buildings.

Buildings in the same way could have model variants. Or faction decals like the Command Centers have.

If models are modified, we should take NProject models as a base, because they have various fixes already applied.

I like the Dozer ones, but these Workers look hideous to me^^
