Please handle GraphEdit._on_end_node_move

[qbx2]

I cannot reposition GraphNodes, and the offsets are reset when I update GraphNodes.

My solution:

1. Add this to _init_connections() in DialogueNodesView.gd

   if not _graph_ui.is_connected("_end_node_move", self, "_on_end_node_move"):
       assert(_graph_ui.connect("_end_node_move", self, "_on_end_node_move") == OK)

2. Add this to DialogueNodesView.gd

   func _on_end_node_move():
   var node = _selected_node._node
   _dialogue.node_move_request(node.uuid, _selected_node.offset)

3. Implement node_move_request in DialogueDialogue.gd

   func node_move_request(uuid, offset):
   var node = _node_by_uuid(uuid) as DialogueNode
   node.position = offset

I tested it and it works, but I think the author could add better code to handle this.
