Gargoyle doesn't ignore ports bound to ipv6 addresses by default.

[btaub]

It looks like gargoyle misses ipv6 ports when auto-checking for valid ports to ignore. Adding 80 and 443 to .gargoyle_config works fine, but those two ports get missed by default. Note that for recent versions of Apache, the default behavior is to bind using ipv6.
