No self notify2

Hi Habbie,

I've made this in a separate branch because i expect that you simply drop the other patch (although they could work together).

I'm using ComboAddress here with 0 as the port. We don't have a port here, but the comboaddress compare function should filter out any problems with the string not fully matching (easy with ipv6).

I've also ended up using a vector<> for the local addresses because stringtok() didn't allow me to use the set<>.
