d/doxygen-1.9.3-x86_64-1.txz: Upgraded.
n/network-scripts-15.0-noarch-18.txz: Rebuilt.
netconfig: when DHCP configuration is selected, also add hostname labeled
loopback entries to /etc/hosts. We don't want to have to rely on something
else providing correct name service in order to be able to reach our
machine through its own hostname. This was a regression since the netconfig
shipped with Slackware 14.2.
Thanks to Zexuo.
