Syntax: path=PsychtoolboxConfigDir([subDir])

Purpose: Look for a folder for storing Psychtoolbox preferences; create if
necessary.

     When called without optional 'subDir' argument, the path to the  
     root configuration folder is returned (and the folder optionally  
     created if it doesn't exist yet). When 'subDir' is given, the  
     path to the subfolder 'subDir' inside the root configuration  
     folder is returned - and the 'subDir' created inside that folder  
     if neccessary. Subfolders are useful to group related  
     configuration data, e.g., all settings for DAQ toolbox, all  
     display calibration settings, etc.
