Organize scope-list in Subnet Matrix-frontend

[Gro-Anita Vindheim]

NAV as IPAM (part 1)
-------------------
Our NAV-monitored network is growing (due to the NTNU merger, but also because we use more and more RFC1918-addresses),
and we find ourselves adding scopes in seeddb to monitor utilization.

We plan to use the subnet matrix-view to get an overview, but the front-end (start page showing multiple scopes) becomes rather messy when NAV har more than, say, 3 scopes.

We would like the start page to be organized f.ex in three columns:

<Official IPv4 adresses> <RFC1918-addr> <IPv6 addresses>

and each of these columns sorted by cidr.

I think this is an easy task, but it would be very useful to us :)
