[DQSD-Users] "df" for word definitions (take 2)

[David Blume]

Sorry, all.  I'd left an alert() in there, had the dictionaries in the wrong
order, and didn't know that there was formatting whitespace hidden in the
XML response.  Here's a second cut of the file that takes those points into
account.

    Search for word definitions.  Recommended it is used with ":|df" in localaliases.txt, so that "word:" brings up its definition.
