Add superclass of vtkObject called vtkObjectBase, put reference counting to vtkObjectBase, make all Register and UnRegister methods to be virtual and take vtkObjectBase as an argument, fix wrapping for Tcl and try to fix it for Python and Java. This was tested on Linux and Windows. Also, containers are now subclass of vtkObjectBase. Eventually commands should also be.

ENH: STL is not used anymore if FTGL_DO_NOT_USE_STL is set (a lightweight STL-like vector has been provided, as well as a new charmap struct)

ENH:Screwed my head on straight and got contouring/clipping working right for quadratic hexs and quads
