And not crash when one gets removed!
4.7 critical fix.
This is to be fixed properly in time for 4.8, to reuse the solution BT editor has.

Fixed up the details panel name area to be aware of in world component editing.
Fixed up usage of the details panel name area to use new enum based usage flag for name areas

I fixed the crash found in the material editor, but discovered some rendering issues. Backing this out for now.

Remove duplicated implementations of DrawConnection in subclasses that draw non-curved splines, overriding ComputeSplineTangent instead
Upgrade note: Any editor plugins that contain a FConnectionDrawingPolicy subclass will need to update calls to DrawSplineWithArrow, DrawConnection, and DetermineWiringStyle

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.

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.

The display name, filter string, and tooltips for the property editor (and associated detail customizations) are now stored as FText rather than FString. This allows us to remove SLATE_TEXT_ARGUMENT from the detail customization widgets.

* Moved Slate.h into SlateBasics.h and began shifting less commonly used headers into SlateExtras.h.
* Slate.h now simply includes SlateBasics.h and SlateExtras.h.
* Slate.h includes a deprecated warning now to indicate that SlateBasics.h + specific includes should be used instead.
* Moved dozens of inlined functions using Slate widgets into .cpp files to avoid header dependencies.
* All code samples now include SlateBasics.h and SlateExtras.h so future shifts will not break most those projects, but not trigger the deprecation warning of including Slate.h.

- 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
