adding fedora 3.7.0 to travis
Fixes the issue with image path to ‘add.png’ breaking when i18n site prefixes are in use. url() should not be used to get file paths. This is a documented issue, fix found here: https://api.drupal.org/comment/26869#comment-26869 . Note that the “better” solution in the comment following is not actually better - it does not work when Drupal is installed in a subdirectory and not in the server’s root.
