Add gui tool for fixing error 60000

 In order for your game to connect, you must configure the DNS settings of your DS.\
 By default, Entralinked is configured to automatically use the local host of the system.\
 This approach is not always accurate, however, and you may need to manually configure it in `config.json`.\
-If you receive error code `60000` when trying to connect, erase the WFC Configuration of your DS and try again.\
 After tucking in a Pokémon, navigate to http://localhost/dashboard/profile.html to configure Game Sync settings.
