UE-9699 - Fixing all the places we were setting the asset size to 0 explictly, the new default reasonable size is .1, all asset pickers now just use the default, unless they're the content browser.

UETOOL-213 - Minimize Slate FString -> FText conversion (remove SLATE_TEXT_ATTRIBUTE)
This fixes any editor/engine specific code that was passing text to Slate as FString rather than FText.
[CL 2399803 by Jamie Dale in Main branch]
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.

#jira UE-1240 - Can have more than one instance active of the open level asset picker

#UE4 You can now use the level "Save As..." dialog to overwrite existing levels. If they are in memory, they will be unloaded before proceeding.

[CL 2280595 by Bob Tellez in Main branch]
Includes the following engine-level changes (among others; biggest change is enabling world assets by default):
CL 2252857
added dynamic allocations for path finding, removed hardcoded limit of 128 polys in path corridor
CL 2256142
Added support for native arrays in JSON object converter.
- Permissive in treating arrays of size 1 and scalars as equivalent
- Excess elements in JSON are ignored. Serialization succeeds but a warning is logged
CL 2256073
Fixed a bug in ARecastNavMesh::BatchRaycast resulting in NaN hit locations
CL 2253797
#UE4 More aggressively setting RF_Public and RF_Standalone flags on maps and ensuring world names match package names. This is necessary because umaps are currently being managed outside of the content browser and it is causing a few issues. Also, packages containing maps now synthesize asset data when the package contains absolutely no asset data (probably because the UWorld in it was not RF_Public at the time it was saved due to a previous bug).
CL 2258142
#UE4 Added a GC during map load that reclaims memory allocated during load/init. This is needed to finish the load on low-memory devices in games that allocate more memory after load.
CL 2247003
Added homing to ProjectileMovementComponent
- Homing requires both a bool and a target component to be set, the strength is determined by a customizable variable
- Both homing and gravity are now applied in the new virtual function "CalculateAcceleration"
CL 2247249
Moved the homing modification to acceleration occur in a separate function specifically for homing
CL 2257043
- Guard net dormancy calls against executing on clients, based on thread with DaveR and JohnP; This particular case was the result of an intentionally client-authoritative actor calling the dormancy functions via inheritance
CL 2245629
#UE4 - fixed json TryGetNumber to round negatives appropriately
CL 2255312
#UE4 Enabling World Assets by default.
CL 2260956
Analytics ET now loads HTTP at StartupModule so the module will be available during ShutdownModule to flush events
CL 2245571
GenericTeamAgentInterface can now retrieve attitude of an agent towards a given actor #UE4
- Made PerceptionSystem's sight sense take advantage of that
CL 2246897
Fixed perception listeners not being removed from the PerceptionSystem on Owner's end play #UE4
- addresses TTP#343392
CL 2260634
added more debug data for NaN in crowd simulation
CL 2248387
Added possibility to debug multiple EQS queries with GameplayDebugger. #ue4
Fixed network replication from bandwidth point of view for data in GameplayDebugger. #ue4
CL 2253281
Added additional information to the visual logger for UBTCompositeNode::DoDecoratorsAllowExecution
- We now keep track of whether a decorator allows execution, in addition to the existing log for not allowing execution
CL 2255310
#UE4 The world browser module now listens to WorldAdded/WorldDestroyed events instead of WorldInit/WorldCleanup events. Worlds can be initialized without being the editor world and this handles that case.
CL 2258256
#UE4 Replacing the SOpenLevelDialog with a new generic SAssetDialog. This dialog will be used as a generic Open or Save As dialog for assets.
