Chatterbox Improvements

[vroom]

Now you should be able to use all of the linking conventions used elsewhere on the site. You should also be able to use CODE tags to correctly display code segments.

This is great! Just one minor bug: apparently it's doing the long-string-breaking before parsing the HTML entities. In my first two tests, it just happened that I typed & # 0 9 3 ; to get a right-bracket, and a space got inserted right between the 9 and the 3, breaking it, and I ended up with something like "[test 3;" in the chatterbox :-)
