Omicron Gamma sun has bright center

[BC46]

https://github.com/FLHDE/freelancer-hd-edition/issues/245 mentioned JFLP adding spines to all suns to remove Spew warnings. The spines have been removed in a later commit. However, it seems that the Red Dwarfs (and probably the Red Giants) still have a bright center which is not what these planets had in vanilla.

I had a look and this appears to be caused by the lens_glow lines. To fix this while not generating Spew warnings, dummy lens_glow lines will have to be made here as well.
