Add realgud fringe arrow colors

[rocky]

I'm not a designer so feel free to adjust the colors.

Thank you! I see you made similar pull requests for some other themes,
so I assume you don't use alect-themes. So I changed the colors a bit 😄.
Let me know if my assumption was wrong, and you don't like
these colors. Also I added more realgud faces.

Thanks for adding and looking over and adjusting. I do use the alect themes.

They are on the computers I use on the which is why I thought of it. And I see they are now updated via melpa. So I tried each of the 4 to see what they look like with the fringe arrows. Looks good.

I bounce back and forth between themes, since I don't have a strong preference. When some color scheme doesn't work out, I often just switch theme than investigate what's wrong. But knowing that there's a good chance that there's someone like you back there that will fix it if I investigate, means that in the future I'll be more likely to pay attention to, report and possibly fix problems I have in the future.

So again, thanks.

Oh, if you see that something looks ugly in alect themes, feel free to open an issue.

BTW I'm really impressed by realgud! Such a huge project for an Emacs package. And your innovative approach to package loading (I mean load-relative) is very interesting!
