Trigger needs to deal with IPv6

WINTER, I MEAN IPV6, IS COMING

The following needs to be done to implement proper IPv6 support: 

* ACL parser needs to be enhanced to properly validate and sort v6 addresses
* Command/config parsing elements need to also handle IPv6
* icmp6 types/codes
* ipv6 headers
* support for Juniper "next-header"
* More I'm sure!
