Godot editor's control for selecting the
script property of a Node.
Similar to EditorResourcePicker this Control node is used in the editor's Inspector dock, but only to edit the
script property of a Node. Default options for creating new resources of all possible subtypes are replaced with dedicated buttons that open the "Attach Node Script" dialog. Can be used with EditorInspectorPlugin to recreate the same behavior.
Note: You must set the script_owner for the custom context menu items to work.
