BPython:

- tentative fix for scripts with CR/LF endings and split lines:
    in 2.32, the ac3d and vrml2 exporters, for example, had lines
    split with '\\\\' and so gave syntax errors when executed on Win
    platforms, because the scripts bundled with Win binaries had dos
    line endings.

- Chris Keith has written code to execute Python scripts from the
  command-line, with '-P ' switch: "blender -P filename":
    a Blender.Quit function was also added, so Blender can quit after
    running the script (end the script with Blender.Quit()), but there's
    still work to be done in this part, including adding more functions,
    to load / save .blend files and to run scripts.  More testing and
    discussions are necessary.

Thanks Chris, for both your contributions and your patience, since I
wasn't available to check / commit this for a while.
