[quackle] dictionary display

Wed, 10 May 2006 14:09:53 -0700

Unless I'm doing something very stupid that I haven't noticed,
the dictionary list/save option in Quackle appears to always
produce the same list regardless of which word source is
selected.

So I hacked up this so I could have a look at the word lists
and do some random checking for quality:
