[Zenmap] Terminal Problem due to Nmap Runtime Interaction

[Jay Bosamiya <jaybosamiya () gmail com>]

Hi All!

If I were to open Zenmap from terminal, and then Cancel a running scan,
then the terminal is in an unusable state (typed characters are not
echoed after closing Zenmap). I am forced to close the terminal and open
a new one.

This is caused because a SIGKILL is sent to Nmap when we cancel a scan.
I think that this should be a SIGTERM so as to allow for a clean shutdown.

Attached is a patch that does this.

Note: There is runtime interaction when you run Zenmap from terminal.
You can notice this by pressing keys on the terminal when a scan is
running.
I think that there should *not* be any runtime interaction in this case.
Since not a lot of people run Zenmap from terminal, I think it'd be a
low priority but should probably be done at some point of time in the
future.

Cheers,
Jay
