Comment 6 for bug 1445580

I marked the dialer(app) task as Incomplete, as I'm not sure it requires a change.

I also added an indicator-network task as it's not clear the indicator should allow flight-mode to be enabled when an active call exists. This should absolutely be prevented during an emergency call, but I would argue that it should be prevented during any active calls.

I'm not sure if there's a separate Unity/framework mechanism which would prevent "ear-induced-flight-mode", but maybe this could be accomplished via the proximity sensor as an alternative ( only if foolproof ).
