This fix to HtmlEntity prevents throwing exceptions on numeric entities greater than 255 -- it makes them return nil, like non-numeric entities do. 

To Reproduce: start the squeak WebBrowser on http://www.yak.net/ --
the korean, russian, and thai characters way at the bottom of the page
are represented this way.  Or just doit: on the subject of this message.

e.g.  
This used to throw exception:
           HtmlEntity valueOfHtmlEntity: '#50557' 
and with the fix, it just returns nil.
(#50557 is Korean Hangul YAK)
