[PATCHv7 0/9] gitweb: avatar support

[Giuseppe Bilotta <giuseppe.bilotta@gmail.com>]

One more attempt at adding avatar support to gitweb.

The most significant change since the previous iteration is the addition
of a picon provider, and its use as default from gravatar.

Most other patches were changed to follow Jakub's suggestions. In
particular, the two-line author/committer information was refactored
to reduce code duplication, with the benefit that it could also be used
in 'tag' view.

Giuseppe Bilotta (9):
  gitweb: refactor author name insertion
  gitweb: uniform author info for commit and commitdiff
  gitweb: use git_print_authorship_rows in 'tag' view too
  gitweb: right-align date cell in shortlog
  gitweb: (gr)avatar support
  gitweb: gravatar url cache
  gitweb: picon avatar provider
  gitweb: use picon for gravatar fallback
  gitweb: add alt text to avatar img
