Allow disabling the "Autonomous address-configuration"

Description
You should add a checkbox allowing to disable the "Autonomous address-configuration", setting the rtadvd option "pinfoflags" to 0 (or "") for the interface.
In my case, i need to disable this to keep the router advertisement but not to have autoconfigurated addresses or subnets delivered (because i have several different subnets linked to the same interface)
My thought was to add this as a choice from the drop down on the DHCP server page.
The config code currently does not take this flag into consideration which it really should.
Would a "Advertise router Only" in the dropdown do the trick? Unmanaged being autoconfig. Assisted is both and managed is DHCP6 only.

Added a "router" type that sends pinfoflags as being "". From the confusing documentation this might need to be "l" which is link but not autoconfig.
Needs testing.
- Status changed from Feedback to Resolved
Confirmed that my Macbook with 10.5 only has a link-local address when set to router-only. you can Still enable DHCP6 ofcourse. Some clients will start a client regardless from the bits set in the advertisement.
pfSense does this too, and it officially breaks the RFC that it should only start when the router advertisemnt says so. I can't care enough.
