CP: Improve an OpenSource Python project and submit changes upstream

CoachPotato is a well known open source project that is used to download things from newsgroups (usenet). We need these modifications done: - Make CoachPotato work behind a reverse proxy. Suppose we want to access CP at https://server/coachpotato instead of directly in http://server:someport as it's usually done. - Notice that we are going to be using https. Probably will imply changes in CP to avoid browser warnings. - Add a "user directory root" that is a soft-chroot, meaning that no user data cannot be written above that directory and that in general no data can be read above that directory. Once all changes are done we need them submitted to the official development team so they can be integrated into the official version. The developer is allowed to sign the work with his real name, etc, same as any other open source project one contributes to. The work will be licensed using CP's license.
