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

* 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.

- 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)

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.

+ Tweak the MaxPixelsPerInput value to work better when snapping is turned on.
+ When the snap interval is set to 0, don't try to snap.

+ Fixes an issue where making a section too small would make it infinitely large and fixes an issue where zero sized sections could no longer be resized.

- Duplicate now works properly in the asset view.
- Consolidated common asset actions into the asset context menu and removed the duplicate code from all asset type actions that had implemented them. The affected actions are Edit, Reimport, Find in Explorer, and Open in External Editor. The latter three actions are only visible for imported assets.
- Added IsImportedAsset() and GetSourceFilePaths() to IAssetTypeActions for use by the context menu.
- Compressed the bottom matter on the context menu by removing section headers and compressing Source Control options into a sub-menu (when connected, otherwise there's just a "connect" menu entry).
- Added lots of icons! (The missing ones are TTP'd)
- Fixed FAssetEditorManager::OpenEditorForAssets to work in a useful fashion. IAssetTypeActions::OpenAssetEditor() already took in a UObject array, so it is up to the class's asset type actions to decide how to handle editing multiple assets. (It appeared to be before, but wasn't really).
- Removed the "Details" option from the context menu (since it's redundant when there's a guaranteed "Edit" option)
- Consolidated all skeleton-related actions into AnimationEditorUtils and removed the duplicate code from FAssetTypeActions_SkeletalMesh and FAssetTypeActions_Skeleton
- Compressed the Paper2D sprite options for textures into a submenu
- Renamed "New" to "Create" in content browser
