[PATCHv8 0/7] gitweb: avatar support

8th iteration of my attempt to implement avatar support for gitweb. Only minor changes from the previous version: the removal of a couple of patches that need to be discussed some more, and some tune-up suggested by Jakub.

Giuseppe Bilotta (7):
  gitweb: refactor author name insertion
  gitweb: uniform author info for commit and commitdiff
  gitweb: use git_print_authorship_rows in 'tag' view too
  gitweb: (gr)avatar support
  gitweb: gravatar url cache
  gitweb: picon avatar provider
  gitweb: add empty alt text to avatar img
