STB comments organizer

Seattle Transit Blog comment toggler and sorter; may add tagging feature later

The comments in the Seattle Transit Blog can number in the hundreds, in response to one article. This makes it hard to read comments, especially replies that arrive days later. This extension will: - collapse all comments, unless included as URL hash, to show just the author and date of comment - expand a collapsed comment by clicking close to, but not directly on, the displayed author and date - sort root comments in order of the most recent descendant comment.
