Add "Any Quality" icons for train stop naming

[c00lguy95]

I would like to be able to use "any quality" icons in my train stop names. The reason is that I want to have train stops on Fulgora for dealing with scrap of any quality, as well as train stops that handle only normal quality scrap while following my preferred naming convention of "Loading - [scrap icon]" "Unloading - [scrap icon]". I can get around the current limitation by naming my mixed-quality stations something like "Loading - [scrap icon] Mix", but I would prefer to be able to use an "any quality" icon instead to stick with my naming convention.

If somebody could add this feature to the game, I would greatly appreciate it. Thanks!
