An `Attachments` view now accepts a `sortable` property. Manual sorting is only enabled when the corresponding collection doesn't have a comparator. jQuery UI sortable must be enqueued for sorting to work. see #21390, #21809. git-svn-id: http://core.svn.wordpress.org/trunk@22101 1a063a9b-81f0-0310-95a4-ce76da25c4cd
