[REL] OLC 'Gold' MkIId

[onelifecrisis]

I've made a JSGME mod which will update OLC 'Gold' from MkIIc to MkIId.

MkIId is a small cosmetic update; the changes are:

• Slightly modified the partial cloud texture.
• Made it easier to tell the difference between "poor" and "moderate" visibility conditions when the sky is overcast (they looked almost exactly the same in MkIIc).

Get the MkIId update here.
