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).
