* Multicast delegate Add* calls now return FDelegateHandles, and Remove* calls are now all deprecated, except for a new Remove function which takes a FDelegateHandle.
* New FConsoleManager::RegisterConsoleVariableSink_Handle and UnregisterConsoleVariableSink_Handle functions which work in terms of FConsoleVariableSinkHandle.
* Timer calls which don't take FTimerHandles are deprecated.
* FTicker::AddTicker now returns an FDelegateHandle and is removed by an overloaded Remove function.
* DEFINE_ONLINE_DELEGATE* macros now define _Handle variants of the Add/Remove functions which return/take handles.
* Various other handle-based registration changes.
* Some unity build fixes.
* Some simplification of delegate code.
* Fixes for lots of existing code to use handle-based registration and unregistration.

- data reset for new PIE sessions (or for each new data loaded from file). This feature is disabled by default.
- fixes for "stick to new data" feature, to work better with zoomed data, etc.
- tweaks and fixes for movement on timeline with keyboard
- fixed time range issues on timellines

- SEditorViewportClient now has an additional optional parameter in its constructor for the SEditorViewport that the client is attached to
- SBasePoseViewport, SDestructibleMeshEditorViewport, and SPhATPreviewViewport were all updated to inherit from SEditorViewport (previously just inherited from SCompoundWidget)
[CL 2398765 by Dan Hertzka in Main branch]
- Filters can be presistent even between editor sessions (option for this in settings)
- Option to filter logs by owner class

Introduces the concept of "Active Ticking" to allow Slate to go to sleep when there is no need to update the UI.
While asleep, Slate will skip the Tick & Paint pass for that frame entirely.
- There are TWO ways to "wake" Slate and cause a Tick/Paint pass:
1. Provide some sort of input (mouse movement, clicks, and key presses). Slate will always tick when the user is active.
- Therefore, if the logic in a given widget's Tick is only relevant in response to user action, there is no need to register an active tick.
2. Register an Active Tick. Currently this is an all-or-nothing situation, so if a single active tick needs to execute, all of Slate will be ticked.
- The purpose of an Active Tick is to allow a widget to "drive" Slate and guarantee a Tick/Paint pass in the absence of any user action.
- Examples include animation, async operations that update periodically, progress updates, loading bars, etc.
- An empty active tick is registered for viewports when they are real-time, so game project widgets are unaffected by this change and should continue to work as before.
- An Active Tick is registered by creating an FWidgetActiveTickDelegate and passing it to SWidget::RegisterActiveTick()
- There are THREE ways to unregister an active tick:
1. Return EActiveTickReturnType::StopTicking from the active tick function
2. Pass the FActiveTickHandle returned by RegisterActiveTick() to SWidget::UnregisterActiveTick()
3. Destroy the widget responsible for the active tick
- Sleeping is currently disabled, can be enabled with Slate.AllowSlateToSleep cvar
- There is currently a little buffer time during which Slate continues to tick following any input. Long-term, this is planned to be removed.
- The duration of the buffer can be adjusted using Slate.SleepBufferPostInput cvar (defaults to 1.0f)
- The FCurveSequence API has been updated to work with the active tick system
- Playing a curve sequence now requires that you pass the widget being animated by the sequence
- The active tick will automatically be registered on behalf of the widget and unregister when the sequence is complete
- GetLerpLooping() has been removed. Instead, pass true as the second param to Play() to indicate that the animation will loop. This causes the active tick to be registered indefinitely until paused or jumped to the start/end.

Fixed issue with visible 2d graphs after closing LogVisualizer
Removed LogVisualizer tool from experimentals so it's a regular tool inside Develoment Tools sub-menu now
Few other minor issue fixes in LogVisualizer tool
[CL 2385317 by sebastian kowalczyk in Main branch]
Made sure everything was using FText rather than FString, and also updated the property editor API to return tooltips as FText rather than FString.
[CL 2373917 by Jamie Dale in Main branch]
Includes following engine changes:
Getting display metrics only once at construct time when using SSafeZone. GetDisplayMetrics is expensive in Windows so it is impractical to call it every frame.
- Some AI API improvements, mostly switchig pointer function parameters to references.
- minor refactor of UCrowdFollowingComponent's queryinf functions:
- IsCrowd*Enabled functions refactored to IsCrowd*Active
- implemented IsCrowd*Enabled that return acrual values of relevant properties
- Added a function to CrowdManager to query for location of agents neighbouring given agent
Added support for PS4 touchpad-based cursor
You can now choose to skip synchronously scanning for asset data in object libraries and just use the data that is currently in the asset registry. The data will be refereshed automatically later once the global scan completes. The only applies to non-commandlet editor instances.
Crash fixes for trying to access NULL Metal surfaces on IOS
