* 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. #codereview robert.manuszewski [CL 2400883 by Steve Robb in Main branch]
