-	Use hexadecimal numbers in substution names

WARNING:

Do never use the compile time option: -DADD_FILES.

This runs on Linux by accident and will cause mkisofs crash
on a Posix compiant system.

The reason for this crash is:

Mkisofs makes the assumption that the pointer that is returned by 
readdir() points to static data that has the maximum size of
a struct dirent. This may be correct on Linux, but is definitely not 
true on Solaris.
