Ctrl-C annoyance

[alex medvedev <alexm () pycckue org>]

hi,

i do not use nmap frequently, nor do i scan very often...
but when i do i am always surprised why nmap does not report anything when
Ctrl-C is pressed and simply runs a cleanup.

when scanning slow networks or firewalls that filter everything nmap may
just sit there for many minutes.

here is a small patch that prints out the ports "collected so far" when
the Ctrl-C combination is pressed.

when Ctrl-C is pressed 3 times it simply quits nmap.
i didn't bother to check what i broke, but i made currenths global
in main.cc
