The file selector for saving plots always starts in the R program directory.  It
is standard for Windows programs to start the file selector in the most recently
saved-in directory.

Steps to reproduce:
1.  > plot (x)   # for some data x
2.  Right click new plot, choose "Save as postscript..."
3.  Choose a different directory (e.g. "My Documents\R\foo.ps")
4.  Again, right click the plot, selecting "Save as postscript..."
5.  The file chooser will open, with the R install directory as the starting
location

Expected Behaviour:
The chooser dialog should start in the most-recently used directory.
