[FREELDR]
- Set the partition count to 0 for a floppy drive so it can be told apart from a cd-rom drive
- Add a last-chance sector size detection algorithm based on the partition number
- Add the same detection code to the xbox code too (it is essentially the same as what was already there just with more comments)
- Change DiskNormalizeSystemPath so it doesn't try to "normalize" a floppy boot path
- Fixes bug #5233
