Added the DockingWindowDefaultLocationEventArgs.FloatingLocation property that specifies the floating location of the docking window when e.ShouldFloat is set in a DockSite.WindowDefaultLocationRequested event handler.
Improved the cleanup of open document references.
Improved key processing to allow child controls to handle keys like Esc, thereby preventing the dock site from handling them.
Improved the DockSite.PrimaryDocumentChanged event to not fire until the end of a batch MVVM items source update.
