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.

Change summary:
- Added UBlueprintNodeSpawner::ImportTarget to store/serialize an object reference to allow for resolving action namespace scope on selection.
- Modified UBlueprintFieldNodeSpawner::SetField() to determine and store the import target object reference for a field-based node spawner type.
- Modified FBlueprintNodeSpawnerFactory::MakeMacroNodeSpawner() to determine and store the import target object for a macro instance node spawner.
- Modified SBlueprintActionMenu::OnActionSelected() to auto-import the associated namespace after selecting an action item containing a valid node spawner.

Member references now store information about the class that owns the reference.
Field and variable node spawners now optionally take the class that will own the nodes that they spawn.

Change 3209340 on 2016/11/23 by Ben.Marsh
Convert UE4 codebase to an "include what you use" model - where every header just includes the dependencies it needs, rather than every source file including large monolithic headers like Engine.h and UnrealEd.h.
Measured full rebuild times around 2x faster using XGE on Windows, and improvements of 25% or more for incremental builds and full rebuilds on most other platforms.
* Every header now includes everything it needs to compile.
* There's a CoreMinimal.h header that gets you a set of ubiquitous types from Core (eg. FString, FName, TArray, FVector, etc...). Most headers now include this first.
* There's a CoreTypes.h header that sets up primitive UE4 types and build macros (int32, PLATFORM_WIN64, etc...). All headers in Core include this first, as does CoreMinimal.h.
* Every .cpp file includes its matching .h file first.
* This helps validate that each header is including everything it needs to compile.
* No engine code includes a monolithic header such as Engine.h or UnrealEd.h any more.
* You will get a warning if you try to include one of these from the engine. They still exist for compatibility with game projects and do not produce warnings when included there.
* There have only been minor changes to our internal games down to accommodate these changes. The intent is for this to be as seamless as possible.
* No engine code explicitly includes a precompiled header any more.
* We still use PCHs, but they're force-included on the compiler command line by UnrealBuildTool instead. This lets us tune what they contain without breaking any existing include dependencies.
* PCHs are generated by a tool to get a statistical amount of coverage for the source files using it, and I've seeded the new shared PCHs to contain any header included by > 15% of source files.
Tool used to generate this transform is at Engine\Source\Programs\IncludeTool.
