NOTE: Old tutorials not deprecated (yet), but widget highlights in old tutorials will stop working with this change!
Added new Blueprintable UEditorTutorial object.
Added suite of widgets and details customizations to display tutorials.
New system is available on command line switch -NewTutorials.
Slate changes:
Tag names are now stored in SWidgets, rather than simply being discarded.
Removed STutorialWrapper in favour of using Tags.
Added Tags to more multibox widgets, so virtually all can now be picked.
Added SWindow::HasOverlay so we dont attempt to add overlays to widows that cannot have them.

#UE4 Moved asset thumbnail dirtying code out of ContentBrowserSingleton and into AssetThumbnail.cpp. Updating thumbnails is not the responsibility of the Content Browser since many systems use thumbnails now.
