periodically "pings" the other end to keep ssh session alive. This
helps recreate state in the firewall state table if it is cleared
when rules are reloaded, which in turn prevents installer from
hanging.
* RuleSetView.cpp (RuleSetView::contextMenu): fixed bug #2407141
"label markers". Color label text set in Preferences was not used
in the contet menus where user can actually apply those colors to
rules.
* ObjectManipulator.cpp (ObjectManipulator::duplicateObject): fix
bug #2303486: "Operation of duplicating firewall should switch
policy". When firewall object is duplicated, the GUI should
automatically open policy of the new object rather than keep
policy of the original open. At the same time, reset lastModified,
lastCompiled, lastInstalled of the new firewall instead of keeping
copies from the original.
* instDialog.cpp (instDialog::testFirewall): Check to make sure
paths to ssh and scp utilities are properly configured in
Preferences before running install. Show aprropriate error dialog
to the user if path to ssh or scp is not configured.
algorithm used to decide which interfaces of the host or firewall
object to use in a rule when this host or firewall object is found
in source or destination.
