Merge pull request #10 from DALnet/master

Auditorium mode+svstag+akill+rakill fixes
Fix pasteo in find_userban_exact.

The logic for checking whether a CIDR userban already exists had a
missing "continue;" line, making the function behave incorrectly for
IPv4 akills.

Also make the code more readable while we're at it.
