Luna hates a lack of color

[ListenerJubatus]

I also posted this on the forum, but somehow my upgrade from Flux 1.5 > ModernBB 3.7 > Luna 0.8 missed something and forgot to add color columns to the rows for the forum.

The worse part is that forum-related tasks (including looking at the index page or editing these forums from Backstage) without this column causes it to break. There should be a fallback, and it shouldn't be erroring out like this.
