Fix references to namespaces with simple names.

Doxygen's autolinking does not work  for objects that contain just one
"::" at the front of the name.  The  fix is to remove the "::" and add
an explicit "\ref" command.

This fixes some  doxygen warnings: "warning: explicit  link request to
'foo' could not be resolved".
