Removed the warning " [StringUtils] WARNING: Invalid HTML entity in

'Berny & STKRudy85' (we only support &#...; type HTML entities)"; #364.

The reason for this warning message is that irrXML already decodes "&"
(in attribute values) - so even though the '&' is encoded correctly in
the xml as '&', STK only receives a '&' from irrlicht, which then triggers the
warning message. On the other hand, irrXML does not decode &#...; hex
values. 

So short of changing our encoding of "&" I don't see another choice
except just removing this warning.
