FIX: if the 'hostname' and 'nslookup' commands were not found from their HOSTNAME and NSLOOKUP cache definition, hard-coded values were used instead, thus causing pb if the corresponding progs were not in the PATH (RunCommand). Now use FindProgram() to be sure to find both, otherwise do nothing and set the site name to "unknown" (arbitrary. could be empty string ? or error ?).
