final php versions of fwPack and fwUnpack

[Frank Leahy]

Many, many thanks to shaosean and Brian Yennie for providing php 
versions of fwPack and fwUnpack.  I cleaned them up a bit, added some 
error handling, and tested the final code.

I've put the final code up on my server at 
http://photoalbum.backtalk.com/code_snippets/fwPack_fwUnpack.php.txt

Richard, maybe you'd like to add this code to your fwPack/fwUnpack 
stack?

Thanks,
