[vtkusers] Rotate vtkCubeAxesActor

[Sebastien Jourdain]

Hi Michka,

the vtkCubeAxesActor will always be axis aligned no matter what, unless you
update to vtk6 and create your own set of base vector for it.
If you checkout the current version of the source code, you can look at the
test made on the CubeAxis to see how to do what you try to achieve here.
