[PATCHv6 0/8] gitweb: gravatar support

A new iteration for my gitweb gravatar patch series. This one includes a bunch of new patches, some of which make sense regardless of the gravatar support (particularly patches #3 and #7).

Significant changes from the previous iteration are:

* the feature has been renamed to 'avatar', and 'gravatar' is a possible
  value for it (currently the only sensible value, other than '');
* an 'alt' attribute is added to img tags, to be more friendly towards
  text-only browser; no special text is put there, only the avatar
  provider name (i.e. 'gravatar', currently);
* the last patch adds avatars to signoff lines.

I also trimmed the Cc: list for the series, because it was getting very long and I started feeling like I was spamming around by including everybody ever commented on the series. Please don't feel left out ;-)
