BUG: Update VTK minimum version (for release)

If you look at the version number for VTK for the 19 april 2011,
the VTK version is set to 5.9.0, so this version number makes no sense.
I updated the version to 5.10.0, which is known to work with VTKGlue.

Bug reported by Norman K Williams on the ITK mailing list.
