Add magit faces

This is not an attempt to support all Magit faces. As @belak says in #57, there are complications, especially regarding how to handle diffs since they use different shades of red and green. The goal here is to avoid colors inconsistent with the theme as much as possible (see before pic).

I think you may have meant #57. It looks pretty good to me. I also appreciate you providing screenshots. It makes it much easier to see differences and definitely helps speed up getting stuff in.

I'm not complaining, but I'm curious how you picked the colors (it's perfectly valid to say trial and error ;)). I can see (just as an example) that in the top picture names are red but in the bottom, either blue or cyan was used.

@belak
I am not a designer, so I wouldn't have a much better answer than I picked the colors that I liked and changed the ones I didn't.

For instance, in this particular case, red was too attention-grabbing for my eyes and it was stopping from focusing on the commit messages itself, so I decided to choose a more neutral colour.

That works for me. :) Thanks for your contribution!
