Add 'edit node genkey' button to Crown Qt UI
As a Crown QT user I want to be able to edit the node genkey provided by the wallet automatically when creating a new SN/MN through the UI. Until now, only alias and IP can be edited, but the user needs to navigate to .conf to be able to edit the genkey.
This feature is specially useful for users that receive genkeys from hosting providers. It will make setup easier for both the provider and the end user.
