ICMPv6

[mdpugh]

The drop down for the ICMP Type field in ICMP firewall rules doesn't reflect version 6 options (which are vastly different, of course).  Any chance this can be fixed in a patch or minor release?  This doesn't seem like it would require much coding.  If I should fix something like this (an effort to get my hands dirty), how do I submit it?
