"Add Node..." from expert mode should automatically center on the newly created node

[bitnapper]

The expert mode adds "Add Node..." in the "Tools" menu. It creates a new node at a given location. If the location of the newly created node is not in the field of view users get confused. To avoid that I used to center the field of view after creating the node by pressing "3" (zoom to selection).

Usually if one creates a node one also want to edit it. So in my opinion after creating a node this way josm should automatically focus on that node. I'm not sure if there are reasons why anyone doesn't want behaviour (I can't imagine why anyone would want that) but if there are, one could also add an option to change the default behaviour (with autofocus or without).

If I can help with further explanations please don't hesitate to contact me. I'd be willing to explain via voip, skype or show it via teamviewer.
