[Tools] Better dumping

Browse source 
*Remove option to ignore errors and abort right away.
 In the end what's the point if you end up with corrupted backup.
*Always create partial.idx before running on errors.
*Allow forced partial dumping on exFAT with large space, by creating the correct patial.idx file
*Some cleanup
