Added icon size control to DataResultViewerThumbnail GUI and size changing mechanism in ThumbnailViewNode.
Added workaround to force update of IconView when changing icon size. Also added "thumbnail" text to the drop-down.
Fix issues with thumbnail page displays not being in sync with the current global user-selected thumnail size.
Refactored so multiple instances of DataResultViewerThumbnail each maintain their own icon size.
Modified Case to not pull appName from Version statically; instead it now asks the MainWindow for its title and saves that as appName.
