cosmetics, "about" page

Thanks to Kevin
small changes in 6RD GUI
Change of order of nvram vars - previous order cause mksquashfs to segfault!
64 bit cstats
cookies expire much less frequently
Implement quiet-dhcp, quiet-dhcpv6, quiet-ra options & GUI
fix escaping of ` in nvram --set mode

Future proof ipt_account.c for newer kernels (thanks rmerlin)
include iptables-save & ip6tables-save in router image
DHCPv6-PD listen to WAN RA as per RFC 3633.  Otherwise no default route set
Allow WAN RA to be disabled in DHCPv6-PD case
After talking to a UK ISP it isn't necesarily the case that
DHCPv6-PD ISPs will also do RA
dnsmasq2.67cs6 - generally keeping up to date
remove bpalogin & heartbeat.c old telstra stuff
remove bpalogin heartbeat stuff from Makefile
Don't enable IPv6 on eth0, eth1, vlan1 - IPv6 will live on the bridged instances
So 'all' is disabled but default has ipv6 enable so *new* interfaces will get
IPv6 - This simplifies the routing table
Separate ipv6 & ipv4 forwarding enable functions - no real difference
easier to read code
quiet-dhcp,dhcp6,ra options now use single nvram var dnsmasq_q

Bitfield bit 0=quiet dhcp4, bit 1=quiet dhcp6, bit 2=quiet RA
Remove unused variable compiler warning qos.c
