Headers are updated to contain any missing #includes needed to compile and #includes are sorted. Nothing is removed.

MAJOR FEATURES + CHANGES
==========================
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.

Also deleting Localization Dashboard's ILocalizationServiceProvider, as this class now exists in the LocalizationService module.
[CL 2564754 by Joe Conley in Main branch]
- Created the FDownloadLocalizationTargetFile Localization Service Operation, which is handled in the OneSky plugin via the FOneSkyTranslationExportWorker.
- Changed OneSky settings to use the OneSky ID for project instead of project name string (OneSky allows multiple projects to have the same name).
- Removed ProjectGroup setting. Only used when creating a project, should just ask for it in the Create Project UI, when it comes time to make one.
[CL 2564198 by Joe Conley in Main branch]
- Implements the OneSky Project Group, Project, File, and Translation APIs, minus delete commands, etc.
- The communication with OneSky works, but the interface between the Localization Service module and the OneSky plugin about what general Localization Service Commands map to which OneSky commands needs to be implemented.
- Some debug code remains, and some clean up still needs to be done
- Some minor changes to Localization Service module
