Minor fix/suggestion

I humbly suggest to make the save/load page wrap around between the first/last patch.
Also, the manufacturer ID in disassemble_backup.py seems to be outdated.

I made a git commit, saved it as diff, then gzipped it to have the forum allow the file upload. :smiley: - is there a more straightforward way to do this?

More straightforward solution: pull request on github :slight_smile:
