Additional Domain Fields: Support mandatory/compulsory checkboxes/values
Currently there is no mechanism in WHMCS' additionaldomainfields.php to make a checkbox mandatory (EG: for accepting CIRA or Nominet terms of registration). This means that customers can continue to check out a domain registration despite not agreeing to mandatory terms. (For .CA domains, this means that the registration will fail as they apparently enforce at the point that WHMCS attempts to submit the registration, but it would be better to block this at order time)
Please add support for a mandatory value for a field (this could be universal due to the way HTML forms work) so that I could specify "Mandatory" => "checked" or "Mandatory" => "YES" for a text box, or similar.
