Got initial CSRF token framework implemented and sample implementation added in Special:Logout; removing Javascript compression engine from aggressive_optimize_html() and instead calling JavascriptCompressor class from js-compressor.php

<?php

class Text_Wiki_Render_Plain extends Text_Wiki_Render {
    
    function pre()
    {
        return;
    }
    
    function post()
    {
        return;
    }
    
}
?>
