Network connectivity indicator

[oster]

We need an indicator to know the status of the connection to the netflux network (connecting to signaling server, connecting to peers, connected, disconnected, acting as a gate to the network, etc.)

[oster]

I re-open this issue since the current indicator does not provide enough information.

I am fine with the current icons, but I would like to have additional informations (Am I successfully connected with the signal server, with other peers in the network, etc.). It could be provided with tooltips or with an additional panel that appears onclick or onhover on the icon.
