This changes the default generated wallet to be a HD wallet.
We also add a helper class to configure newly created wallets from QML.
This finishes up the new wallet panel to have all the visible features
actually do something.
This finally starts the replacement of the new-account dialog which is
very last century.
Now we have a nice looking panel showing the options and the extra space
is used to make this easier to navigate.
Not all functionality is made available yet, more to come.
