NSD 3.1.0 released

New version of NSD. It supports NSEC3 by default, has a "hide-version" configuration setting, to stop NSD answering from CHAOS class version requests, has bind2nsd 0.5.0, has some bugfixes resolved and reports source and zone for denied AXFR attempts. Some operational notes: the default locations of nsd.db, ixfr.db and xfrd.state are changed to the /var/db/nsd/ directory.
