Unescape a string that has been HTML-escaped

  CGI::unescapeHTML("Usage: foo "bar"
<baz>")
     # => "Usage: foo \"bar\" <baz>"

this seems to only decode  lt, gt and amp entities:

irb(main):003:0> CGI::unescapeHTML("&eacute;lan")
=> "&eacute;lan"

you should have a look at http://htmlentities.rubyforge.org/ if you want
to decode other entities, too.
