Input forms that need validation will have AJAX requests
performed to get validation decisions live.

All but a few important and common form fields perform
generic validation; these will need a back-end handler
in the future in order to have them validated through AJAX requests.

Information is conveyed on focus and blur for both
errors and successes.

In particular, implement a validation API for registration,
where a client makes AJAX calls to the endpoints requesting
validation decisions on each input. Responses are strings
dependent on the type of validation error; if no error,
then empty string to indicate OK.

We have recently discovered that for any SSO Provider configured to skip
the registration form, we were auto checking the terms of service box,
which is a legal faux pas. Since IBM is planning to launch imminently and
is depending on this feature, we need to remedy this situation for enterprises
whose SSO Provider is configured to skip registration.

This PR hides all of the registration fields except TOS for this scenario
and disables the autoSubmit functionality that typically happens when skipping
registration.

Includes code for testing to be removed in the next commit.

Previously, there was no catch for the AccountValidationError
exception raised by the account creation function. If, for some
reason, the user made it past the first check for a duplicate
username/email, then the exception was raised, uncaught, and
crashed the server.

When authenticating using an SAML IdP, gather additional user
data besides what is standard. Requires admin to input JSON
in settings to recognize the additional user data.

Turns out if the string literal starts on the next line after the
translation function, then the translator comment is lost.  So, either
close up short strings, or add a dummy empty string on the first line to
concatenate with the real string.

Ugh.
