* landed code for viewing topics in a conference, and for adding a topic

Browse Source 
(first workout of HTML Checker code)
* modified the dictionary implementation to use a trie system rather than
  a set of HashSets, and also started using a new, much smaller dictionary
* general bugfixes and cleanup on other items as needed

The file "webster2.dict" was produced from the word lists supplied as "web2"
and "web2a.gz" in the /usr/share/dict directory of the Debian "miscfiles"
package (GNU miscfiles version 1.2). The following commands were used to
produce this file:
The file "en-us.dict" is taken from the "american-english" word list supplied
in the Debian "wenglish" package. A small amount of processing was used
to produce this file:
zcat /usr/share/dict/web2a.gz | fgrep -v ' ' > temp.dict
cat /usr/share/dict/web2 temp.dict | tr '[A-Z]' [a-z]' | sort \

I, Erick Branderhorst <branderhorst@heel.fgg.eur.nl>, took over the
wenglish package but I don't know where the list of words is from. If
it is uptodate or copyrighted or whatever.
Welcome to web2 (Webster's Second International) all 234,936 words worth.
The 1934 copyright has elapsed, according to the supplier. The
supplemental 'web2a' list contains hyphenated terms as well as assorted
noun and adverbial phrases. The wordlist makes a dandy 'grep' victim.
This package was debianized by Herbert Xu herbert@debian.org on
Sat, 8 Feb 1997 22:16:50 +1100.
