DialogRssWatchExtender extends DialogRssWatch for XBRL databases.
It is separate from the xbrlDB __init__.py module so that it can be removed when
compiling server versions where Python has no GUI facilities. The imports of GUI
facilities would cause compilation of the server-related modules to fail, otherwise.
