IPv6/DHCP PD Enabled by Default

Receiving a Prefix via IPv6 DHCPv6 should really be enabled by default. Right now I have to figure out how to roll out this change manually to many in-production cnPilot routers to get dual-stacked. If there was a software version available that changed this behavior, this process would be much simpler and would expedite adoption of the new Internet Protocol that we all should be rolling out anyway.
