Fix invalid entities in listclient xml

This fixes a bug where listener Referer or User-Agent strings containing
a sequence like `&T;` was not escaped properly and therefore made the
whole XML document invalid.
Injecting new XML nodes (<foo></foo>) was not possible, it seems in the
worse case all it could cause was that the XML failed to parse.

Fix #2255
