[PATCH v2] gitk: Add a "Copy commit summary" command

From: Beat Bolli <dev+git@drbeat.li>
Date: Jul 16, 2015, 15:29 UTC
Message-ID: <1437060565-4716-1-git-send-email-dev+git@drbeat.li>

When referring to earlier commits in commit messages or other text, one of the established formats is

    <abbrev-sha> ("<summary>", <author-date>)

Add a "Copy commit summary" command to the context menu that puts this text for the currently selected commit on the clipboard. This makes it easy for our users to create well-formatted commit references.
