COMP: TranformIOBase unused GetTypeNameString function.

This function was declared in an anonymous namespace in the .hxx file, then
used by the derived classes.  This does not work with ITK_MANUAL_INSTANTIATION
and causes and unused-function warning when the object file does not contain
one of the derived classes.

The functions were made into static const inline class members.

COMP: TransformFileWriter unused AddToTransformList.

This addresses warnings such as

/home/matt/progs/ITK2/Modules/IO/TransformBase/include/itkTransformFileWriter.hxx:165:13:
warning: unused function 'AddToTransformList' [-Wunused-function]
inline void
AddToTransformList<float,float>(TransformBaseTemplate<float>::ConstPointer
&transform, std::list< TransformBaseTemplate<float>::ConstPointer > &
transformList)

by using explicit instantiation to give a better hint to the compiler as to
what specialization to use.
