This PR adds the class rtl on body when the language is RTL in order to use any .rtl .something .
It is added in component.php as well as error.php. Code is similar to index.php. It allows adding specific .rtl .something in the rtl.less files.
It also changes the order of loading of the .rtl .something present in the template_rtl.less when they are saved into template.css by generatecss.php.
This because these rtl classes should override their counterpart as set from various .less files when importing.
