[Rd] Open .ssc .S ... files in R (PR#8690)

[timh@insightful.com]

----- Quick summary:  

In the File:Open dialog, please change
"S files (*.q)" 
to
"S files (*.q, *.ssc, *.S)" 
and show the corresponding files (including .SSC and .s files).

----- Background
This is motivated by the following query to R-help:

So there is a workaround.  But it is odd that the "S files" option
doesn't actually include what are probably the most common S files.
