Don't render syntax of specific plugins

[jorbig]

I adjusted renderer.php to let it stop rendering bible references (that are normally shown in a tooltip by the bible plugin).

    //handle plugin rendering
    function plugin($name, $data, $state = '', $match = '') {

        if ($name === 'bible') {
            $this->doc .= $match;
            return;
        }

        /** @var DokuWiki_Syntax_Plugin $plugin */

But maybe it's an idea to have a config setting where we can enter plugin names that need to be excluded from rendering?
