Make pkglint really happy.
Add IGNORE_URLS code from agc@:
"If a URL is specified in IGNORE_URLS then all entries listed in
 pkg-vulnerabilities that match that URL will not be reported when
 audit-packages is run.  Running audit-packages -v will display the
 details of all entries skipped if IGNORE_URLS is set."
Add a sample audit-packages.conf detailing all the options we now support.
Update to 1.46
