Add a possibility to bind the RadToolBarTray and generate RadToolBars. By design the RadToolBarTray is created more like a Panel, not like a typical ItemsControl.
The overflow button should have an option to show only when it is needed.
Implement DragAndDrop in terms of allowing a reordering of the ToolBars in the ToolBarTray and moving toolbars from one tray to another.
When the Orientation of the ToolBar is Vertical, in Windows8Touch theme the control is not sized properly. Available in LIB version: 2014.3.1326
