For Niggle 1.3 (http://www.ozemail.com.au/~msteveb/niggle/)

The SIMPLE dictionary is an english word list which contains 41524 words.
Unlike the ENABLE and OSPD3 dictionaries, it doesn't contain many of the
more obscure words, so it may be more appropriate for the casual player.

This is version 2 of the SIMPLE dictionary which removes a number of words
which did not appear in either of the other two dictionaries.
