Feature: Add set Nas IP and Credentials to settings.

[JAKAMY]

Hi after the new number update changing the Nas ip address in the xml files to adapt to tailscale new ip when on the go doesn't work anymore and says no credentials found when downloading a title.
The current credentials are also encrypted and can't be updated manually.
Please add the option to add a default Nas IP in the settings and the option to edit the credentials/path? 
Tailscale changes the lan nas ip but doesn't support nas discovery, it was working before in old versions before. I can access it in file explorers like cx file explorer.
Thanks
