        keyboard support for extending/shrinking comment context
        https://bugs.webkit.org/show_bug.cgi?id=54612

        ctrl+shift+up/down will extend/shrink the comment context when
        a comment is focused or when one is being edited.

        Also, switch over to using keydown instead of keypress events.
        This lets us share code for handling escape and other key events.
        Also, keypress is evil and should die.
