* Removed SECTOR_SIZE in the read-only part of the intel partition scanner;

Browse Source 
however, it's still used in the write part.
* Made the read-only code block size agnostic. Only tested with an Apple
  iPod so far, and it recognizes its partition fine now. Next test on real
  hardware.
* Cleanup.
