Hi!

This package stores the user configuration under ~/.config/Qtrac Ltd./,
which has at least two problems. First when I'm looking for the config
files, that name does not immediately say anything to me, and it's not
documented in the man page either. And second because it's named after
the company behind it, if at some point it was to be abandoned and
taken over by someone else, it will get renamed, or it might not
represent the current maintainer which would be misleading.

It would be nice if the configuration file could be moved to something
more obvious and stable like say just ~/.config/DiffPDF.conf or
~/.config/DiffPDF/DiffPDF.conf, or something along those lines.

Thanks,
Guillem
