Import User with Higher Role

I went digging into the code a little bit and came up with this solution, all modifications to importer.php:

At the top where you are assigning variables, add:
$editable_roles = array_keys(get_editable_roles());

And then after line 221, after the new/modified user array of roles is defined, add the following:

if (!empty(array_diff($role, $editable_roles))) {
	$error_string = 'You do not have permission to assign this role';
	echo '<script>alert("' . __( 'Problems with user:', 'import-users-from-csv-with-meta' ) . $username . __( ', we are going to skip. \r\nError: ', 'import-users-from-csv-with-meta') . $error_string . '");</script>';
	$created = false;
	continue;
}

I have not tested with cron or frontend but it appears to be working fine on the backend.

An additional improvement to the backend page would be to ad id’s to the form fields. This way they can be targeted through css to hide and clean up the UI for options that are not important for non administrators. I’ll be glad to do this if you like and send you my revisions.
