uiDialog.draggable: override containment and scroll options

[binduck]

In ui.dialog.makeDraggable, when calling uiDialog.draggable method, it could be very useful to override containement and scroll options.

        options: {
             .....
             draggable: true,
             draggableOpts: {
                scroll: true,
                containment: 'document'
             },
             .....
         },
         .....
         .....
	self.uiDialog.draggable({
            cancel: '.ui-dialog-content, .ui-dialog-titlebar-close',
            handle: '.ui-dialog-titlebar',
            containment: options.draggable.containment,
            scroll: options.draggable.scroll,

We don't expose any plugin's full API through another plugin. If we expose all of these options, dialog's API would instantly triple in size. If you need more control over your dialogs, you should use the dialog plugin directly.
