- This checkin eliminates use of all <Module>Classes.h files in Engine, with the exception of UnrealEdClasses.h
- Compilation speed-ups for all of the modules affected, now that they are including what they use
- No effective changes other than C++ includes

#jira UE-16415 - The origin of a BSP brush stays in place while youÆre editing the brush in Geometry mode, often leaving the origin (and default rotation point) floating off in space.

#jira UE-16419 - If you right click on a vert to snap a pivot of a brush to that location, it will automatically reset the pivot back to the origin after your next mouse click.

#jira UE-16405 - Hitch occurs when undoing BSP manipulations
Summary of changes:
- Added 'fuzzy map' for quick look up of nearly equal FVectors, improving the BSP rebuild algorithm from O(n^4) to O(n*m) where m is much smaller than n.
- Added 'fuzzy map' for quick look up of nearly equal FPlanes, improving plane merging from O(n^2) to O(n).
- Changed TTransArrays in UModel to regular arrays, to remove a lot of transaction modifies during BSP rebuild.
- UModel array allocations are now allocated upfront where possible, instead of constant dynamic resizing.
- Optimized algorithm used by UModelComponent::GenerateElements to reduce allocations and simplify map lookups.
- Removed call to ULevel::CommitModelSurfaces in UModelComponent::PostEditUndo, which was causing an enormous amount of unnecessary work on each undo operation. It is now done, as ever, by UWorld::Tick.

#jira UE-12430 - BSP brushes that have been brush clipped cannot be copied and pasted between maps
#jira UE-12122 - Editing duplicated BSP brushes also edits the original brush
The new UModel is created as an inner object of the new Brush, meaning that it has no external path and hence imports correctly.

- FQuatRotationMatrix(GetActorQuat()) is ~4x faster than FRotationMatrix(GetActorRotation()), due to latter form's FQuat->FRotator conversion and different matrix construction using Sin/Cos.

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