pytave: oct-py-types.cc annotate

annotate oct-py-types.cc @ 415:9bf8ba050122

Replace all remaining Boost.Python references * exceptions.h (pytave::error_alreadY_set): New exception placeholder class. * __py_struct_from_dict__.cc, oct-py-eval.cc, oct-py-types.cc, oct-py-util.cc, pycall.cc, pyeval.cc, pyexec.cc: Use it in place of boost::python. Remove all #includes of Boost headers.
