This change fixes problems with some compilers recognizing only <vector>,

and others recognizing only <vector.h>;

change from
   #include <vector.h>
to
   #include "stl_vector.hh"
(this now after includeing "cctk.h"), where "stl_vector.hh" is a
new header file that looks at the symbols HAVE_VECTOR and HAVE_VECTOR_H
(defined by Cactus at configuration time) to see what to #include
and whether or not to use an explicit using declaration to bring
vector into the global namespace
