Missing IPv6 support

[Joyez]

It seems that SPARTA do not fully support IPv6,
when adding an IPv6 address in the scope we got an Invalid Input;
and when importing an nmap xml file including an IPv6 host only, nmap scans fails to launch and the IPv6 address is not even shown in the Information tab.

Hi Joyez! Thanks. We know! :)
This is in our TODO list with a low priority. This priority could change if we have many requests for this.

This is a great idea please implement

The main problem here is that most tools that we'd want to run after nmap don't support IPv6. This will lead to several problems.
