Update ShellOpen to handle versioned files; add ShellOpen into SEE-PDF in place of MacOS-specific open. (#1410) ...

* Update PDFSTREAM: integrate ShellOpen into PDF-SEE in place of MacOS specific calls; update how PDFCONVERTER is set to fix bug whereby it was always ps2pdf

* Fix ShellOpen so that if a file to open is versioned then that file is copied to tmp and its filename is changed from foo.pdf;25 to foo~25~.pdf and this tmp is passed to the opener instead of the original file.  This is so that the extension is preserved as the last thing when there are versions.  The extension as the last thing is used by most openers to determine the file type.

* Oops. Checked in the wriong versions of UNIXUTILS(.DFASL) last commit.  Correcting that here.
