Registration List Supports Domain Match

DMH Admins can simply now add domains to the registration list, and all registration requests with emails under that domain will be allowed.

When viewing the Registration List management interface the 'Add' tab allows adding a list of individual emails or a domain. When the domain toggle is selected, the provided domain is associated with a role, account and optionally a company name. Any validated registration request associated with that domain will create a user with those role, account and company name values. The domain configurations can be managed via the 'Domain' tab
