* Added PrefetchVirtualMemory function * Fixed bug where code writing callstacks checks end of module to figure out if address belongs to module * Changed so FileAccessor::CreateMemoryWrite set always allow read because you can't create file mappings that are write-only * Added option to scheduler to force all runs to run native * Fixed so bottleneck class has enter/leave function * Added ScopedReadLock::Enter * Moved LogWriter to its own file * Visualizer - Fixed so when hovering over timeline time under pointer is showing * Visualizer - Fixed so hovering over work records shows name, start and duration * Visualizer - Added context menu item that can show/hide text of process bars * Improved assert message * Changed so lock is not on stack but is leaked to prevent shutdown warnings in debug * Added missing includes [CL 31981637 by henrik karlsson in ue5-main branch]
