Total Git 0.3.58

Avatars: choose your own picture for anyone, or one of 24 built-in ones

- Right-click a commit, the commit details avatar, a pull request row or any
  avatar in a PR window: "Set picture for ...". Choose a file, paste, drop
  one on the circle, or pick a built-in picture.
- A chosen picture beats GitHub, Gravatar and initials everywhere: the graph,
  commit details, the author filter, the sidebar and the PR windows.
- People are matched by commit email or GitHub login. Total Git now learns
  which login goes with which email whenever GitHub says (noreply addresses,
  commit authors, user search).
- The person button in the toolbar lists every chosen picture, to change or
  remove.
- Kept on this PC only, under the data folder's avatars/custom.
