psi build 49 is out

Hi all,

A new psi version, python shell using wxPython, is out
- bug fixes in psi48 version
- some improved code (regular expression)
- psi49 includes two plot modules, psiplot and
psiplotz. These modules allow the plotting/printing of
numerical data (real or complex data) directly from the
interpreter. (see the sceenshot of the psi web page).
