plasma-applet-networkmanager has been superseded by a bunch
of kde4-plasma-nm* packages; only the main one has been included
in regular-kde4 flavour since the switch resulting in the lack of
VPN/mobile connectivity options.

My opinion still is that plasma-applet-networkmanager should be
returned as a metapackage for p7/branch timespan so that images
could be built no matter whether it's sisyphus or p7 at hand.

Oh well.
