[Tools] Better dumping
*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
