This fix makes it so that IPv6 addresses are properly set when using the set, sequence, and save commands and that the IP header and UDP/TCP psuedo-header IPV6 addresses are properly set. To preserve the runtime commands, the `_atoip` function no longer takes in flags to specify converting IPv4/6 addresses, and will try both. It returns 4, 6, or -1 for a valid IPv4/6, invalid address, respectively. Also print IPv6 addresses in UI properly.
