ENT-581 Upgrade enterprise package to 0.39.5

[ENT-334] Add client-side registration form validation.

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.
