multicd.sh - combine Linux ISOS into one

[iomari]

Thanks! It turned out to be a mistake in the code writing the menu entires - I mistakenly assumed that Puppy always had its own folder. It's fixed now in the git repository version.

Cool. Puppy now works, pmagic works, weakerthan works.

The last one still not working is Freedos Full. Reports Invalid Opcode.
