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.
