[RESEND PATCH 1/1] enable cgit to show gravatar for author, committer and tagger

[Jason at zx2c4.com (Jason A. Donenfeld)]

I like this. But I could imagine a bit of backlash against it -- it's
a particular web service owned by a private corporation (Automattic),
and some detractors might argue that an open project like this has no
interest in this kind of proprietary service integration. Are there
any such detractors on this list? If so, we can fill this thread with
some sort of discussion. Otherwise, pending the nitpicks below, I'll
merge it.

This is clever, but potentially error prone.
