Previously the server parameters were each handled differently, e.g. auto-connect was only applied when updating Network.server
and not when Config.autoConnect was updated. Similarly, updating Network.server did not restart the network, leading to >1 connection
when Network.oneServer was set to True before updating Network.server.
Consolidate server parameter updates into a single call, remove the individual setters, and move Config.autoConnect and Config.autoConnectDefined to Network.
'last' property on WizardComponents is now queried from UI, not from the wizard.
This allows the content of the WizardComponent itself to be taken into account.
