Partitioning context

I've just two more (related) points to consider:

- we should probably add an option to recognize files as a hard disk 
and be able to scan the partitions contained therein
- it would be nice if we would recognize if one partitioning system is 
used inside of another

both would be very convenient mostly for users of emulators (such as 
Bochs or Amithlon, the former accesses files as hard drivers, the 
latter has the standard amiga partitioning system inside an Intel 
partition), but I could imagine other useful applications as well.
What do you think=3F

Adios...
