Fixed problem if no file list exists then not create de dl with class
attachments file
Removed jQuery('$files_container').prependTo('#fileupload').addClass('files');
because always files class y created
Added class h3attachment for Attachments Title to prevent anchors on tag h3
Removed compact = True in include "zurb_list_of_attachments.html" at wiki_view
to show the list of files.
Removed include "zurb_attach_file_form.html" to remove the attach button because
the list of attach contain the add files button.
