Change summary: - Moved base definition of UK2Node::HasExternalDependencies() up one level to UEdGraphNode (to avoid blind casts in a context where we may not necessarily have a UK2Node subtype). - Updated subtype headers that override HasExternalDependencies() to relocate the declaration into the class declaration's 'UEdGraphNode overrides' section (for clarity). - Reverted previous UBlueprintNodeSpawner::ImportTarget solution in favor of using node dependencies; this allows auto-import actions to scale more easily to all existing node subtypes and avoids data duplication. - Modified SBlueprintActionMenu::OnActionSelected() to utilize the new method for determining which namespace(s) to auto-import after executing a node spawner action in response to a context menu item selection (UE-146803). - Reverted FBlueprintNamespaceUtilities::GetPropertyValueNamespaces() back to its original 5.0 signature so that it uses a TSet<FString> for the output rather than a TArray<FString>; this fits in better with input to other APIs. - Renamed FBlueprintEditor::FImportNamespaceParameters to FImportNamespaceExParameters (for clarity). - Changed the 'FBlueprintEditor::FImportNamespaceParameters::AdditionalNamespaces' member to a TSet<FString> containing *all* namespaces to import rather than limiting to only additional ones. - Reverted FBlueprintEditor::ImportNamespace() back to its original 5.0 signature and added/implemented FBlueprintEditor::ImportNamespaceEx() as the "extended" version that allows for batched imports and future customizations. - Revised existing FBlueprintEditor::ImportNamespace() call sites to utilize and/or conform to the extended ImportNamespaceEx() API where appropriate. #jira UE-146803 #rb Benjamin.Fox #preflight 623cf3a433709ff50128e8d4 [CL 19505118 by Phillip Kavan in ue5-main branch]
