Comment 4 for bug 1644091

The mechanism behind is apparently that the password in `settings.json` is overwritten with the hash of the password<ref>https://superuser.com/questions/113649/how-do-you-set-a-password-for-transmission-daemon-the-bittorrent-client-server</ref> which is a good idea, but requires a good implementation and documentation. Both the configuration file and the `settings.json.tmpl` are undocumented. The purpose of `settings.json.tmpl` is unclear and change to it don't seem to have an effect.
