STYLE: Replace postfix with prefix increment, decrement (++, --)

Applied to the root of ITK source tree, at the GNU bash prompt:

    find . \( -iname itk*.cxx -or -iname itk*.hxx -or -iname itk*.h \) -exec perl -pi -w -e 's/  (\w+)\+\+;/  ++$1;/g;' {} \;
    find . \( -iname itk*.cxx -or -iname itk*.hxx -or -iname itk*.h \) -exec perl -pi -w -e 's/  (\w+)\-\-;/  --$1;/g;' {} \;

Excluded itkConceptChecking.h, as it is intended to check both the prefix *and*
the postfix forms. Excluded the unit tests, as they might intentionally test
the postfix forms.

Follow-up to:
pull request #2493
commit f81578b
"STYLE: Replace postfix by prefix increment in `for` loops in Core/Common"
