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.

#rb Benn.Gallagher
Change 2841977 on 2016/01/25 by Ori.Cohen
Fix object type customization so that it's only enabled when custom is selected. (Accidently broke this in recent change)

Minor optimization by avoiding recreating FNames repeatedly in constructor
Change 2842169 on 2016/01/25 by Benn.Gallagher
Fixes to animBP compiler and instance to store and double buffer internal machine state weights on the instance. So they can be queried cross-machine without issue.

Change 2842390 on 2016/01/25 by Ori.Cohen
Fix in world editing of BodyInstance not working.
No longer serializing Scale3D as this is allways initialized in InitBody.
No longer overwriting MassInKg and renamed to to MassInKgOverride which better reflects what this variable does.

Change 2843579 on 2016/01/26 by Marc.Audy
Only update replication when it actually changes
Don't check calling SetIsReplicated if the class cannot replicate, instead output an error message
Fix spelling in comment

Inline Get Component functions in TriggerBase
Change 2844003 on 2016/01/26 by Zak.Middleton
#ue4 - Fix FMath::Fmod(X, Y) sometimes returning small negative values for positive X and Y due to float imprecision. Added tests to math tests at startup to check this, and also to better handle results close to Y. Wrap the ensure on Y=0 within a conditional so a breakpoint can be used during debugging (to distinguish between zero and very small input).
#codereview Laurent.Delayen
Change 2844005 on 2016/01/26 by Zak.Middleton
#ue4 - Convert uses of fmod() and fmodf() to use FMath::Fmod() instead.

[CL 2855709 by Marc Audy in Main branch]
Fixed hard-to-read documentation tool-tips in Blueprints (UE-8467)
- Changed SCS tool-tips to use the new simplified dark-text-on-white-background styling
- Made "Hold Ctlr+Alt" easier to read on a white background
[CL 2425847 by Ben Marsh in Main branch]
New look and feel for Slate tool-tips
- Tool-tips are now black on white so they stand out from the rest of the editor
- Increased tool-tip font size by one point; increased the amount of padding
- Only regular text-only tool-tips and documentation tool-tips are affected. We may update the various customized tool-tips later on.
[CL 2419520 by Ben Marsh in Main branch]
SCS Editor now shows a root actor that you can select and see properties.
Draging and dropping components to the graph from SCS editor creates Getters.
Add components drop down has more common entries and better naming for some.
[CL 2419383 by Ben Marsh in Main branch]
Find-in-Blueprints now uses the same search data for both Find-in-all-Blueprints and Find-in-Blueprint. That searchdata is no longer stored in the asset registry, it is stored in the DDC and is managed by a new class. Searching is multithreaded to reduce overhead on the main thread during long searches in large projects.
virtual UEdGraphNode::AddSearchMetaDataInfo which sets base find-in-blueprints metadata and can be overriden with more detailed search data.
#change UEdGraphPin::GetDefaultAsString will return the text value as string if set
Added FBlueprintEditorUtils::GetEntryAndResultNode, moving most of the functionality from FBlueprintGraphActionDetails::SetEntryAndResultNodes to the new function
Added FBlueprintEditorUtils::GetGraphDescription to get graph descriptions from their metadata
Added FBlueprintEditorUtils::GetNodeByGUID to find nodes using their Guid
Blueprints now cache their search metadata on compile, this is a CPU intensive process and can no longer occur every time the Asset Registry queries for the Blueprint's tags
#change Fixed an issue with finding a pin type's icon (UK2Node_Variable::GetVarIconFromPinType) where we would search for a class we already had available.
Added an overridable function to UEdGraphNode to collect Blueprint search metadata.
#change FJsonObjectConverter::UPropertyToJsonValue is now available outside of the .cpp
#change Rewrote how Find-in-Blueprints works both for local and global searches, now uses Json to resolve a variety of format issues and also to make it much more extensible.
#ttp 290376 - K2: Ability to search (find in blueprints) important pin values
#ttp 298599 - ROCKET: TASK: K2: Search results should indicate where the instance is located in the results page (construction script, event graph, custom graph)
#ttp 304819 - Blueprints: Editor: L10N: "Find in Blueprint" needs to work with other languages
#ttp 308572 - UE4: ANIM: K2: Searching doesn't work for anim nodes right now
#ttp 316678 - UE4: BLUEPRINTS: SHADOW: Default values are not searchable
#ttp 318180 - UE4: K2: Cannot search for spawnactor using find in blueprints
#ttp 320141 - UE4: K2: Find in blueprints does not find functions declared in another blueprint (if the function isn't called in that BP)
