I don't like this being hidden in the toolbar menu.
The other items in the toolbar menu are ~settings or generic actions
independent of the current request. This one is dependent on the
current request, and even the active "tab"... does not make sense
to show this when the lightning tab is active.
It is more difficult to discover it in the first place than previously,
and it being less visible goes against encouraging hw device users of
using it, which is what we should be doing.
Anyway, this commit just makes it functional as-is.
Previously we added a " *" suffix to distinguish the selected/main server
in the list. However in case of an .onion address, anything we put as a
suffix inline is elided/truncated - as the address itself does not fit.
Hence we could instead use a prefix - and then why not use an icon.
When exporting a tx as qr code, the prev txs are omitted to save space.
This causes problems with offline signers: software electrum signers will
just warn and then proceed, but hw devices will typically error.
`server.net_addr_str()` cuts off the trailing protocol marker, while `str(server)` has it.
`parent.set_server` then called `ServerAddr.from_str_with_inference` trying to guess the just cut off protocol,
but fails if given an IPv6 address.
The qt, qml, and kivy GUIs have a first-start network-setup screen
that allows the user customising the network settings before creating a wallet.
Previously the daemon used to create the network and start it, before this screen,
before the GUI even starts. If the user changed network settings, those would
be set on the already running network, potentially including restarting the network.
Now it becomes the responsibility of the GUI to start the network, allowing this
first-start customisation to take place before starting the network at all.
The qt and the qml GUIs are adapted to make use of this. Kivy, and the other
prototype GUIs are not adapted and just start the network right away, as before.
Use the app timer instead, so that the tx is not recomputed
on every slider move (like in ConfirmTxDialog).
A similar modification is needed for QML. I started with
Qt in order to get a sense of how it should be done.
