First pass of changing statusbar connectedness

Switching from GCM-only inet condition reports to using our network
validation (captive portal check).

Note that currently the GCM signal is disconnected.  Next step is to
make the bad-network report API trigger a re-evaluation of the network
and get negative reports from the NetworkMonitor.
