2ed0275040 Slate: Re-introduce SlateAttribute.OnValueChanged(). N.B. You are only allowed to invalidate attribute in the callback that doesn't affect the child order or the visibility of the widget.

be0c084a13 Fixed errors re format string / parameter list for various UE_LOGs: 
- number of supplied parameters less or more than the number of specifiers used in format string
  - invalid format string specifiers used
Also changed text of two UE_LOG error messages to match the other ones.

097426f18c Slate: Add update flag for volatile prepass. These widgets always need a prepass in fastpath. Fix issue with collapsed, the desired size was not updated when a parent was also collapsed. Fix the wrong position of elements inside a Retainer when the Retainer moves. Keep an array of all widgets that always need to be updated (tick, timer, paint). That prevents notifying the proxy and the final list once the widget got painted and ensure that all elements are updated.

120469e3b5 Slate: Rename "Collapsed" SlateAttribute to "AffectVisibility". It represent more the intention. If the parent is collapsed, the child SlateAttribute was not updated even if they were marked as "update when collapsed". Update the widget reflector to show the name of the SlateAttribute (only if the widget is live). Call GetRelativeLayoutScale after the attribute are updated.

ee9c7f8dcb Slate: Move visibility flag to WidgetProxy. Keep track of the Collapsed and the Visible state to update the Attribute as in SlowPath. Convert RenderTransform and RenderTransformPivot to SlateAttribute. Make the Visibility attribute update first (needs more work in the SlateAttributeInitializer to enforce it). Update Attribute in 2 steps. Update the Collapsed first (that can change the visibility), then update the "not collapsed" attribute.

a722a0fcc2 Slate: Add option to prevent Slate Attributes from being called automatically on the SWidget. It is useful when the owner of the widget controls the invalidation (ie. ScrollBox). 
Add PrePass invalidaiton. It implies a Layout and replaces the InvalidatePrepass function.

73f1355ee0 Slate: Fix bugs with GlobalInvalidation and SlateAttributes. 
Rework the PreInvalidate algo to make it more clear the order of the different invalidations should be processed.
Add a flag to FWidgetAttributeIterator since MoveToWidgeIndexOnNextAdvance was using Invalid as the invalid state and the last element.
Rework the failed condition for the "Slate.InvalidationRoot.Verify*" to stop the process and only output once the error.
Only add the widget to the FinalUpdateList if an update is needed.

7892f94351 Slate: Update SlateAttribute when building the SlateInvalidtionWidgetList since SWidget may changes their visibility. That implies that the AttributeIterator now needs to move at the end of the newly built array. The code will be moved into a utility function once we do the visibility optimization (visibility flags are not on the FWidgetProxy). Confirmed the correct use of bPauseAttributeInvalidation in SlateAttributeMetadata.

It reduce the number of Layout invalidation that are already processed by the child order invalidation. Add Slate Attribute InvalidationWidgetReason.

c8b2ae9472 Slate: Add SlateInvalidationWidgetList a container, similar to a paged array, that can update the fast path list faster. It uses 2 indexes instead of one. It only rebuilds the elements that are affected by the update. Use FSlateInvalidationWidgetIndex and FSlateInvalidationWidgetSortIndex. FWidgetProxy is currently used but will be phase out soon to remove duplication and improve performance.
