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.

Changed the font used when a font is missing or invalid to be the last resort font, rather than the localized fallback font
The localized fallback font could cause different results based on your culture, and the last resort font makes it clearer that something is set-up incorrectly as it just draws invalid glyph markers for all of the text.

Cleaned up some duplication in UMG text widgets, and exposed the text shaping options
The common properties used by all text widgets that are text layout based have been moved into a UTextLayoutWidget base class, and all text layout based widgets now derive from this.
The options needed to control the text shaping method used by a text based widget have been exposed via the FShapedTextOptions struct. This contains a way to manage these optional (and advanced) overrides. You typically wouldn't change these from the default unless you knew exactly what you were doing (eg, you have a text block containing only numbers).
This change also updates SRichTextBlock to work with an invalidation panel in the same way that STextBlock does

Slate - Improving the way we track references to materials in slate to better keep things alive until they're no longer needed for rendering. Additionally, making it so the we use the material and texture free list when possible when cleaning up things as to not allocate new memory if not required. Concidentually this can help with problems with corrupted memory on destruct as well, because it means the memory isn't really going to become garbage any more.

UDataTable::SaveStructData now writes out dummy data when RowStruct is null

UMG - Making it more obvious what keys do special stuff with anchors in UMG. Fixing the way snapping to anchors works with Control, it now only zeros out the side you're dragging instead of the entire widget, which was silly. Enhancing the designer message system to no longer be based on an enum and instead let arbitrary systems push and pop FText messages. Fixing animations in the anchor drop down to properly animate, broke when we introduced active timers.

Moved the existing atlas visualizer out of the Slate RHI renderer and instead made the resource manager for each renderer implement the ISlateAtlasProvider interface to provide information about its current texture atlases. FSlateFontCache implements ISlateAtlasProvider for the font atlas viewer.
Improved the atlas visualizer and added support for zooming and panning of the atlas pages. This helps greatly when viewing font atlases as they can be as large as 2048x2048.

This addresses a crash when trying to draw text from the render thread.
The extra font cache is managed by FEngineFontServices, and its creation is delayed until it is first needed. In Canvas you now use FEngineFontServices (rather than FSlateApplication directly) which will automatically return the correct cache for the current thread.

Please note that file comments had no purpose in nearly all cases and just added visual clutter. The two files that had meaningful file comments had their comments moved into the corresponding classes. There are still hundreds of file comments left in other files that will be removed over time.
Also cleaned up some random stuff along the way:
- relative paths to public headers within the same module are no longer necessary (automatically discovered by UBT now)
- header guards are deprecated, use #pragma once instead (all compilers support it now)
- space between multiple template brackets is no longer required (all compilers support >> now)
- NULL to nullptr, OVERRIDE to override
- spelling errors, whitespace, line breaks
