Added a feature where you can now add a commented "# Name = " property to QR code configs to import them with a name. If there is no name configured, app will use the first peer's host address as a name.
Improved imports so they no longer replace an existing config if that config has the same name. Instead, they will import with a (number) appended for config name duplicates.
