Save folder is not remembered #6277
Description
Describe the bug
Once I save a file to a particular folder, OpenSCAD should remember that folder location, at least until I close OpenSCAD
To Reproduce
Create an OpenSCAD file, Save it to a non-default location, attempt to Save it again, and note that you are back to the default location
Expected behavior
Once I tell OpenSCAD where I want to save files, it would be nice if OpenSCAD helped me, by remembering the location, rather than forcing me to specify that location repeatedly

Additional context
There have been lively debates about how OpenSCAD deals with source file locations and STL file save locations. My personal preference is that OpenSCAD always remember where I last opened a file, and where I last stored a file. It is the most likely location for the same operation in the future. I would like this to persist across all executions of OpenSCAD, but at LEAST during one invocation of OpenSCAD. I am reporting this as a bug because the current program behavior differs from the program behavior in the past.
