name (boxes.cfg).

* Eliminated use of PATH_MAX in order to ease porting
* Restructured infile/outfile code to eliminate need for access() function
* and improve readability
* Added file type check before reading config file. boxes used to generate
* a weird error message if the config file is a directory
