Some domino related cleanup

 * Removes the hotfix file for domino. Was only being used in some
   places (a potential source of errors) and considering cscott lives
   upstream, it shouldn't be a problem getting fixes merged. Also, we
   seem to be using the "fork and put a link to a git repo in the
   package.json" pattern in other cases.

 * The bug being worked around in the PostProcessor was fixed by:
     https://github.com/fgnass/domino/pull/29

 * Some other minor cleanup.
