Release 1.13

• For Debian/Ubuntu, the .deb package is now the recommended way of installation,
  because it automatically configures cgroups as necessary.
• BenchExec now automatically attempts to use the sub-cgroup system.slice/benchexec-cgroup.service
  if it does not have access to the current cgroup.
  This means that if you followed our installation instructions
  for systems with systemd, there is no need anymore to manually
  put your shell into the correct cgroup.
• Several smaller bug fixes for table-generator:
  #249, #250, #259, #260, #271, #272
• For users of the Python API of RunExecutor,
  different file names can now be specified for stdout and stderr of the tool.
• Some new tool-info modules and updates for SV-COMP'18.
