Allow the type= attribute on the verbatim wiki tag. This attribute does not pass right through. If found, it is treated as the 'Language Type' and alters the output of the verbatim tag slightly. verbatim type='cpp' would render as pre name='code' class='cpp'. This allows JavaScript tools such as SyntaxHighlighter to function properly for any language. check-in: 63d31b04 user: jeremy_c tags: trunk
