set a maximum name refresh time of 20 minutes.
The previous code was strictly correct, but not very practical. self names were only refreshed every 3 days. I hit a situation where the Samba WINS server was restarted after deleting wins.dat and didn't notice some remote subnets (also running Samba). I realised that the complete database wouldn't have been rebuilt for 3 days, which is way too long. In order to recover from WINS restarts we need a much shorter maximum refresh time. (This used to be commit 1d23dd0912e81ff72695bd043e8e2aee32da18a8)
