"me-web?" 0.13.0: updates on Linux arrive through your package manager

- Installing the deb or the rpm now also adds the Arasaka package repository, packages.arasaka.software, so later
  versions of “me-web?” arrive through apt, dnf, zypper or your software centre, like any other program.
- The rpm is now signed. On openSUSE, import the key once with
  sudo rpm --import https://packages.arasaka.software/arasaka.asc
- Removing the package keeps the repository until no Arasaka package is left (purge on Debian and Ubuntu); a
  repository file you edited by hand is never touched.
- The download and privacy pages say so; the repository server keeps no access log.
