        IncludeUrlContentWiki macro for MoinMoin 1.8
        
        Get the content from an URL, process it as wiki markup, and return those
        formatted results. 
        
        I personally use this in cases where I have a web server
        process to dynamically generate content that relies on wiki
        features like macros, smileys, table layout rules, etc.
        
        Usage: [[IncludeUrlContentWiki( http://foo.com/wikimarkup )]]

        Changes:
          11/19/08: Made the read text into unicode so that when the imported text contains a macro,
                    wikiutils doesn't freakout (in function invoke_extension_function).
