REVISION SUMMARY
  Currently `CliInterface::copyFiles()` creates a temporary directory in `/tmp`, upon extraction of one or more selected files.
  This does not scale well on systems where `/tmp` is mounted in RAM, if the RAM is low or if the archive has huge files.
  
  We can simply create the temporary directory on disk. We only need to be sure that the temp dir is created on the same disk where the final destination is (otherwise we write each (possibly huge) file twice).

TEST PLAN
  The QTemporaryDir is created on the same disk where the final destination is, and it autodeletes itself upon destruction.
  Extracting huge files does not fill the RAM anymore.
