Githawk: Add separator between review comments

[BasThomas]

Now only distinguished by avatar. Should probably use the same separation style as comments in an issue / PR.

I was trying to keep the thread UI consistent with PR review threads on GitHub.com. The separator isn’t there so it’s more clear that it’s a continuous conversation. Different threads get separators, a diff hunk, and file.

I’ll enable separators and see how it looks.

That's a good point; on web you have this vertical line, but we can't have that unless we inset the text to the right... which due to size constraints I wouldn't do 😛

Problem Solved :trollface:

so beautiful

[rnystrom]

Gonna say its too busy

I actually think it looks nice with the blue headers where it's "you" -- could we do a very faint grey for anybody but "you"?

@rnystrom 🤔

[BasThomas]

The blue headers are already there; the gray horizontal lines aren't. @Sherlouk

@BasThomas Yea I know! I'm suggesting we don't have the lines, but have a light grey background on all other users 😄
