context menu item for ordering nodes

In the console, add a context menu item on nodes to sort sub-nodes in various ways, but at least on alphabet. That makes working with the console a lot easier for large websites.

Remarks from google groups:

I think it's a good idea, though the 'actual' order of the nodes is relevant. It should be clear if you are seeing the 'actual' ordering or an imposed one. This is the console so some things are more primitive because it is a bare view of the repository.

Nice test for Apache Wicket development knowledge! You will find examples of how to add a link to this menu and invoke a dialog in the existing code. There should be a confirm dialog ("are you sure?"). When sorting the nodes, see if you want/need to use Collators for locale dependant sorting. An example can be found in the class org.hippoecm.frontend.i18n.types.SortedTypeChoiceRenderer. But then the result will be different for different locales that you log in with... maybe not what you want. Maybe there are JcrUtils available to help you sort?
One more thing: on nodes that are not orderable (CND keyword) the menu option should be there, but unavailable for that current node. May be explained with a nice tooltip.
