* Move the show/hide advanced button a bit down the page. * Improve save button caption when creating a role. * Don't show defaults on the basic define roles screen. * Explain the background shading on the advanced roels screen. * Fix the problem with the risks link to Moodle docs. * Help icon by the permissions column heading. * Tables with rotated <th>s, make them vertical-align: bottom. * Rename explain.php and explainhascapability.php to check.php and explain.php * Tool tips on the number headers in the explain table. * Explain table - role names were missing. * Allow link_to_popup_window to work with full URLs.
