The credentials for btcd should be saved by default
Ideally the credentials for btcd should be saved and the connection dialog only shown if the saved credentials are invalid.
We could save the credentials and autofill the dialogs, but i don't want to perform autoconnect since that prevents you from using another btcd if you wanted to for some reason. This is assumming btcd is left unmanaged by Paymetheus. If it's started by Paymetheus as a service, that's another story, and could be made even more streamlined by removing the prompt altogether.
That makes sense. As discussed in IRC, I do think managing btcd from Paymetheus would be the best case. Along these same lines, I don't imagine it would be overly difficult to allow a flag to specify a remote btcd instance which uses the code that already exists today.
