token: [:mail] support or plain array output

regarding the problem of the send email action, see http://drupal.org/node/284036#comment-5691862 for further information.

If you are using email field module, which brings a new cck field for email adresses, and you'd like to use this field (also with multiple values) for recipients, you should implement (per own module or patch) the hook hook_field_info_alter() like in following snippet:

<?php
/**
 * Implements hook_field_info_alter().
 */
function email_send_field_info_alter(&$info) {
  
  if(!empty($info['email'])) {
	$info['email'] += array('default_token_formatter' => 'email_plain',);
  }
  
}
?>

... so the default token output is raw email text.

This is just a quick solution for those who are having similar problem. Modifying system module is usually a bad idea.
Better would be a token for email fields, like [node:YOUEMAILFIELD:mail] so no modification of the system module would be needed and you could use it for recipient field in system's send-mail action.

Unfortunately, i don't know how to implement this, anyone knows?

Nice mate, thanks. But maybe this can break a lot of site installations, because people can let the default formatter be as it is and rely on it that it's automatically rendering as a link.

For contributing, I think an update hook would be neccessary which converts the formatters set up as default explicitly to a link formatter. I cant test this by myself at the moment so I set the status to needs review.
