Sync with nmap 3.95

Changes:

- Updated NmapFE to build with GTK2 rather than obsolete GTK1.  Thanks
  to Mike Basinger (dbasinge(a)speakeasy.net) and Meethune Bhowmick
  (meethune(a)oss-institute.org) for developing the
  patch.  I made some changes as well to prevent compilation warnings.
  The new NmapFE now seems to work, though I do get "Gtk-CRITICAL"
  assertion error messages.  If someone has time to look into this, that
  would be appreciated.
