In order to use new feature user have to change GENERATED_UCLASS_BODY() macro to the new GENERATED_BODY(). Then no constructor is implicitly declared. If there is no constructor declared in UCLASS then PCIP one is declared and defined that passes PCIP down to super-class. On the other hand if there is a constructor declared then UObject system expects to have one of the default or PCIP constructor to initialize a class during loading from disk, default object creation, etc. and it expects that user will declare and define one.
There is a possibility now to create UCLASS with the default constructor (i.e. no PCIP).
New macro is encouraged by standard classes and in-editor wizards templates.

FScopedSlowTask has been refactored to better allow for nesting of slow operations. This allows us to cascade nested scopes and provide accurate feedback on slow tasks. FScopedSlowTasks now work together when nested inside sub functions. Break up long functions that contain calls to multiple nested FScopedSlowTasks with FScopedSlowTask::EnterProgressFrame().
Example Usage:
void DoSlowWork()
{
FScopedSlowTask Progress(2.f, LOCTEXT("DoingSlowWork", "Doing Slow Work..."));
// Optionally make this show a dialog if not already shown
Progress.MakeDialog();
// Indicate that we are entering a frame representing 1 unit of work
Progress.EnterProgressFrame(1.f);
// DoFirstThing() can follow a similar pattern of creating a scope divided into frames. These contribute to their parent's progress frame proportionately.
DoFirstThing();
Progress.EnterProgressFrame(1.f);
DoSecondThing();
}
This addresses TTP#338602 - NEEDS REVIEW: Editor progress bars nearly always just show 100%, don't offer useful indication of progress

Now editor will tick at a decent frame rate while building shaders / caching textures.

* InterfaceCast deprecation version number changed to 4.6.
* Double-underscored identifiers replaced with names which aren't reserved.

- Added links to actual source files. Lots of times intellisense/VA will take you to the less helpful skeleton file rather than the actual source file.

* Cast can be used for every UClass/interface cast:
- Up/down UObject hierarchy.
- From interfaces to UObjects.
- From UObjects to interfaces.
- Between interfaces.
* InterfaceCast has been deprecated.
* dynamic_cast can now be used instead of Cast.
* dynamic_cast between two UType pointers will be equivalent to Cast, but with dynamic_cast syntax and semantics.
* dynamic_cast of references is equivalent to a CastChecked - if it fails, it will fatally log rather than throw a std::bad_cast exception (UE doesn't support exceptions).
* If the two types involved are not UTypes, it should continue to act like a normal dynamic_cast.
* dynamic_cast<void*> works as expected.
* All/many Casts in CoreUObject changed to dynamic_cast to show this behaviour.
* Some refactoring.
