fix: document/fix wrapped HtmlProperty method.
The wrapped method was not documented in reference.txt.
It is now documented in reference.txt. The docstring documented that
it would not break up long words. Fixed by adding
break_long_words=False to prevent breaking string longer than the wrap
length. Wrapping was breaking the hyperlinking of long urls.
Added columns argument to set the wrap length (default 80 columns).
