Before 0.8 is released, the compiled-in list of seed nodes should be updated.
This should really also get onion seed nodes, and potentially testnet seed nodes (IRC stinks).
What about this one, it was scheduled for 0.7 ;-).
Didn't get done for 0.7.... so I edited it so we (hopefully) get it done for 0.8.
