Add logic to notice that the device is offline and notify the
user of this fact on screen.
Repeat checking so we can notify the user that network is back.
This shows in the UI (of the mobile form factor) that the device
is offline and we avoid starting the p2p layer until network
is detected to be there again.
Continuing the 'rework send page' series.
This moves stuff that had no business being on the "Send" page to
live on a new tab instead. Prime example was the 'sweep' module
that creates a transaction we send, but to ourselves. So it's far
fetched that it fits in 'send'.
A peer that has not yet handshaked is now show in this view, giving a
better indication of what is going on on platforms that do not have easy
access to a log file.
This is likely the oldest component in the app and it was
really in need of a rewrite.
The state of peers is shown much clearer now, we use a proper
model in order to avoid the jumping and we use a more safe
way of getting at the data.
