This change is controversial. It changes the behavior of fl_filename_list

slightly by adding a forward slash after every directory name on every
supported OS. Included in this patch is a change in the code that 
lists mounted volumes on OS X Mac.

Apple users, please check. Open FLUID, open the file dialog and
clear the current path. You shoudl see a list of mounted volumes.
