Wrap access denied text in paragraph tag

Good work on this module. It's surprising that this behaviour is not in drupal core.

If I may make a couple of suggestions;

drupal_set_message('Access denied. You must login to view this page.', 'error');
Wrap 'Access denied. You must login to view this page.' in the t function

$return = t('You are not authorized to access this page.');
Change it to
$return = '<p>'. t('You are not authorized to access this page.') .'</p>';
It just makes the page a little more semantic.

Let me know if you want me to provide a patch.

Thanks again.
