using namespace std;
from Riostream.h, which has huge consequences for all of ROOT.
Riostream.h is now a simple wrapper for fstream, iostream, iomanip for backward compatibility; Riosfwd.h simply wraps iosfwd.

Because of templates and their inline functions, Riostream.h needed to be included in headers, too (e.g. TParameter.h), which violated the assumption that Riostream.h is not exposing its using namespace std to headers.
ROOT now requires R__ANSISTREAM, R__SSTREAM, which does not change the set of supported compilers.

Without "using namespace std", several identifiers are now prefixed by std::; e.g. roofit/* source files now have a using namespace std to keep their coding style.
TFile::MakeProject() now generates "using namespace std" to convert the CINT-style class names into C++ ones.

- small mod added to make possible to
  search over directories (check list dir from guitest)
  It's not clear for the moment how to implement it in more general way
- addition to guiviewer.cxx
   // exit program on close window
   Connect("CloseWindow()","TApplication",gApplication,"Terminate(=0)");

hides the real iostream.h.

sliders. The guiviewer uses these new options. Mods by Brett Viren.
