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.
