File::isOnHardDisk() & File::isOnCdRomDrive()

On the mac, File::isOnHardDisk() & File::isOnCdRomDrive() are missing some file system types. Mainly cddafs (audio cd) and udf (dvd)

Maybe more, here is a list:

Ah - nice one, I wish I’d been able to find a list like that when I first wrote the code.
