Docking and UnDocking of toolbar and other controls

Update---------------------------------------- This is an improved version of previos DLL. Now it handles child controls of the container control which is being undocked, plus I've fixed the problem with changing focus. Also I've included test project so you can see how it is suppose to work. Old --------------------------------------------- This class allows to undock any control on the form and drag it around. Furthermore, during Undocked state events will be still received at the same place. It is an emulation of the Microsofts abilities to undock panels (ex VB Properties and Toolbar)
