gitrl-f 0.9.0

• Ctrl and Shift clicks select more than one commit. The pane
  then shows one diff of only those commits, applied oldest
  first. The difftool opens this diff, or one file of it.
• A new column after the subject shows the lines that each
  commit adds and removes. The added lines are green and the
  removed lines are red.
• The text of the total in the diff pane now gives the two
  counts apart, for example "2 files in total (+72/-13)".
• When gitrlf starts from a terminal, it gives the prompt back
  immediately. The --foreground option keeps the prompt until
  the window closes, as before.
• If the difftool does not open, the window shows an error with
  the cause.
• The side branch of the icon is now Olympic Blue.

Packages for Ubuntu 24.04 and 26.04, and an AppImage.
