        tweak line selection in code review tool

        -Improve handling of data-comment-base-line code to deal with
        lines that have multiple values.
        -Make it so that if you click on the line immediately above
        a line that has a comment it will add a new comment instead of
        adding lines to the following comment. If the last selected line
        overlaps existing comment lines though they will still get
        added to the existing comment.
