Provide form field settings options for registrant type

I was running into a similar issue where we would have administrators who need to register other users, but not themselves. I was able to add a permission for "register self" and then added a condition for that permission in the registration_access_people function.

I'm using version 7.x-1.1 and did't try this with the dev branch.

So in registration_module I added a permission to function registration_permission_list()

    "create $type registration self" => array(
      'title' => t('%type_name: Register self', array('%type_name' => $label)),
    ),

and changed function registration_access_people() to account for that permission

  // Me
  if ($account->uid && ($account->uid === $registration->user_uid || !registration_is_registered($registration, NULL, $account->uid))) {
    $people[REGISTRATION_REGISTRANT_TYPE_ME] = t('Myself');
  }

to

  // Me
  if ($account->uid && (user_access("create $registration->type registration self", $account)) && ($account->uid === $registration->user_uid || !registration_is_registered($registration, NULL, $account->uid))) {
    $people[REGISTRATION_REGISTRANT_TYPE_ME] = t('Myself');
  }

The results are:

If user doesn't have the permission of "register self" but has "register other account" they are only presented with the input field and not the drop down. If they have "register other account/other people" they get the drop down between those two options but not the "Myself" option.

I haven't run into any problems with this and can make a patch.

Thanks, helped me out too.
Much cleaner without the dropdown!

Patch is clean and works. Will push to dev. Thanks!
