remove internal URL checking

[GoogleCodeExporter]

apparently some web hosters block an internal http connect from the cgi 
application to the webserver itself. in one case the provider said this is a 
security measure against IP spoofing.

for one of the next releases either a different way of checking an url should 
be found or the whole check can disappear.

Affected method: MyFav::Base::urlAccessible
