This implementation bears some explanation. When we call connectSource() in define_via_dict_dataengine(),
the dataengine will immediately call dataUpdated() with bad data: our word as a source, and an empty set for results.
Once it actually hears back from the server, we'll get back a single definition with markup, OR and empty set of markup tags if
no definition was found. Ugh.
So, first we filter for no definitions, and do nothing if there are none. Then, if we get one, we remove the tags and see if there's
anything left. If not, we tell the user there was no definition found. Otherwise, we print the tag-stripped definition (since I don't
know how to get the KMessageBox.informationList to use the tags).
If there's a better way to implement this, I'm open to suggestion...
