Use LOD1 models

[speed2CZ]

Adds LOD1 model to be used for some units which have the model and textures and look decent enough (like other units LOD1 models that exist)

what's the goal of adding the lod1 in ? to make the transition smoother ? does it help for the GPU ?
It just make unit darker at first. I guess it help making 2 transitions instead of 1 for the lod 2 (guess it's lod 2).
for aeon battleship, it's smoother when you zoom in, but then zooming off it's less smooth. If you mean by smooth : that when you start zooming in, it rapidly change to lod 2.

Low poly models = less load = more FPS
