Don't use <p>-tags for filter-tips

Using <p>-tags for filter-tips is non-standard.

I suggest the following patch to nofollowlist.module:

-   $output .= '<p>'. t('Links to specified hosts will have a rel="nofollow" added to them.') ."</p>\n";
---
+   $output .= t('Links to specified hosts will have a rel="nofollow" added to them.');
