Minor update to Kenmore DHC2 textures

In preparation for the release of Orbx YRC I’ve uploaded a minor update to the Kenmore Air DHC2 textures. The only significant changes are that the external texture is now DXT5 as it should have been (so the prop spinner looks better) and I’ve change the strong green tint on the windows to a minimal gray blue. The link is on the links page as before.
