         * from the @data-url attribute for other tags.
         *
         * The dialog title is extracted from "#appbar h2" (this selector can be
         * changed with a @data-title-selector attribute on the anchor tag).
         *
         * The dialog content is extracted from "form" (this selector can be
         * changed with a @data-selector attribute).
         *
         * Buttons (both <button> and <a>) are extracted from the content and
         * converted into proper dialog buttons.  A button with "cancel" as its
         * class will have its action changed to simply close the dialog, without
         * server processing.
         *
         * After loading the dialog content, a gadjo:dialog-loaded event is
         * triggered on the anchor with the dialog content as argument.
         *
         * Alternatively the server may notice the ajax request and answer with
         * an appropriate JSON response. In that case it should have a 'content'
         * attribute with the HTML content, or a 'location' attribute in case of
         * a redirect.
         *
         * In case of such a redirect, a gadjo:dialog-done event is triggered on
         * the anchor and can be cancelled to prevent the default redirect
         * behaviour.
         *
         * The JSON support depends on the presence of the jQuery Form plugin.
         *
         * Submit is done in place if the $anchor has a data-inplace-submit="true"
         * attribute, a gadjo:dialog-done event is triggered on success, a
         * gadjo:dialog-submit-error event is triggered on failure.
         *
         * Set data-autoclose-dialog="true" to close the dialog box after the
         * submit.
         *
         * Dialog is modal by default, set data-modal="false" for non-modal
         * dialogs.
