12.15.6 get-folder-path and get-user-profile-directory changed

sys:get-folder-path and sys:get-user-profile-directory now return a directory pathname object that represents the directory. In LispWorks 5.0 and previous versions they both return a string. This change makes it easier to construct a pathname for a file in the directory, for example:

(make-pathname :name "foo" 

               :type "lisp" 

               :defaults (sys:get-folder-path :my-documents))
