#241 XMLReader doesn't unescape entities

[Trejkaz]

In org.htmlparser.sax.XMLReader, when a characters() event is fired out, the XMLReader class isn't unescaping the entities found in the text.

Workaround is to write an XMLFilter which does the unescaping on the fly, but the fix probably isn't too hard to add into XMLReader itself.
