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.

Rob asked me to back out GENERATED_*_BODY -> GENERATED_BODY change for now until the "_Validate and _Implementation auto-generation" discussion is over.

Editor - Improving the dropdown used in the editor for enums to have a not entirely transparent background to give it some lift from the background it's on. Give people some visual feedback that they are buttons.
[CL 2447028 by Matthew Griffin in Main branch]
This is more consistent with the other combos, and addresses TTP#347917 - PROJECT BROWSER: Starter Content buttons has a dropdown arrow, but no list.
[CL 2315697 by Andrew Rodham in Main branch]
This ensures that multiple users will not attempt to update the project settings on start-up.
#codereview Michael.Noland
[CL 2315685 by Andrew Rodham in Main branch]
These are now the defaults, which prevent any updating of project settings until changed by the user.
#codereview Michael.Noland
[CL 2314453 by Andrew Rodham in Main branch]
- Add warning bubble to starter content button when Mobile/Tablet is picked
- Add a fake down arrow to make the button look more interactive
[CL 2310662 by Michael Noland in Main branch]
- Add a settings builder/gatherer class that either builds a description of what the meta-settings will change, or actually applies the changes
- Display the pending changes
- First pass on actual settings controlled by the hardware+graphics level meta-settings (very WIP)

[CL 2302104 by Michael Noland in Main branch]
Also removed tabs from the project browser dialogs when they're not necessary. Fixed up some incorrect icon sizes to work with the new layout.
