Noshader Griff's alternate ships

This bundle adds alternates of the coreships like clean and scuffed Cobra Mk1 & Mk3, clean Mambas and Fer-de-Lances and a different Viper model. It is based on the original shader models and textures from Griff's coreships and was remade to go along nicely with the default shipset of Oolite v1.80+ and/or for e.g. Computer with lowend graphics hardware.
