This is a revert of a previous change
but is now possible due to the use of JSON bodies.
This does mean JavaScript is required in the HTML page,
but that will be required for future changes anyway.
Account settings are stored using the WebID as key.
Reason for using the WebID is that this allows faster access to the settings
in authenticated requests.
A consequence of this is that passwords are now always required during registration,
and that there can only be 1 account per WebID.
This adds options for enabling setup to the config folder.
All default configs with permanent storage (file/sparql)
are configured to require setup at server start.
Memory-based configs merely have it as an option.
The IDP behaviour has been changed to move all error related knowledge
to the IdentityProviderHttpHandler instead of managing it
in the Interactionhandlers.
