Refactor the is_rtl() helper into the Gallery_I18n class. This allows checking

for a config value "force_rtl" which will layout the gallery pages in rtl mode
without having to change to an language that is no longer understandable to the
developer.

Adding the line "$config['force_rtl'] = true;" to the config/locales.php file
will make it happen.
