Per-partition info added

- FiwalkReport.pdf now reports per-partition technical metadata, as well as the partition number in the files-list that follows the metadata.
- Added partition info to all the tables (deleted files table, format tables, etc).
- Tested the code on the image with partition (fourpartusb) as well as the single-partition image (charlie). 
- Modified the config file to not report the special files by default,  and set other default settings.
