I think this makes sense, because now all the plugins will be gnome3 gtk3
based, the same way nm-applet is.
I also removed networkmanager_pptp_gnome variation of networkmanager_pptp
package, because i think no variation is needed and gnome support should
be on by default like in other packages.
Without this the openconnect VPN plugin doesn't work:
NetworkManager[830]: <warn> VPN connection 'Foo VPN' failed to connect: 'Could not find openconnect binary.'.
