We also remove support for WiMAX (now unsupported by NetworkManager),
and InfiniBand (Enterprise feature), and the use of
the deprecated NM_SETTING_WIRELESS_SEC property.
With help from network-manager-applet patches by Jiří Klimeš and
Dan Winship.

Currently, if firewalld is not running, then the firewall zone combo is
always insensitive. This would make sense if firewalld was great and we
were to consider it a distro bug to not have firewalld running and
enabled, then users would be able to see the option is disabled and
think "maybe my distro has done something wrong."
But in actuality, firewalld is not really great, only Fedora ships it
and we're not really recommending it to other distros. So hide the combo
if it's not running, else it's just broken on $NOTFEDORA.

Unfortunately, the VPN plugins provide their own .ui files for their
editor pages, so we can't make them look competely GNOME-3-ish. But
the code does try to fix them up a little bit by realigning the
labels.
vpn-helpers.[ch] is nearly identical to network-manager-applet's,
but eventually this code will move into libnm-gtk.
