1） conf.inc :
    Removed  $test_mode_enable
    Removed  $template_check
    Added $mode : available values :  Developing | Product | Maintenance
    	if $mode=="Developing" , test mode will be enabled, and template output php files under /tmp will be overwrite automatically.
2)  Add custom tag features to Render
     you can use delegate/RenderDelegate.inc  to add custom tag handlers.
     @example : if you want to add a tag names "myline".
     add this function to RenderDelegate :
     static function tag_myline($v_str, $data){
         return ‘<hr style=“‘.$v_str.’”>’;
     }
     Then use it in your template file like this way :
     {myeline border:1px solid red}
     Result will be something like this :
     <hr style=“”border:1px solid red>
3) Add DOMRender to /modules/utils
    which can generate HTML code like liberJS does.
     DOM::init();
    _ul(['id'=>'list'],[
  	_li('text1')->css(['color'=>'yellow','border'=>'1px solid black;']),
  	_li('text2'),
  	_li('text3'),
    ],_div(['id'=>'frame']));
    DOM::render_html();
