Add option to initialze settings

[parkmino]

It would be good to have the option to initialize /var/lib/mympd directory. I run it manually once in a while.

Since myMPD 5.6.0 there are some commandline options. I think you want mympd reset_state.

# mympd help

Usage: mympd [/etc/mympd.conf] <command>
Commands (you should stop mympd before):
  certs_create:     create ssl certificates
  cert_remove:      remove server certificates
  ca_remove:        remove ca certificates
  reset_state:      delete all myMPD settings
  reset_smartpls:   create default smart playlists
  reset_lastplayed: truncates last played list
  clear_covercache: empties the covercache directory

I created a wiki page for reference: https://github.com/jcorporation/myMPD/wiki/Commandline-Options

OK, then I will use this option. I tried 'mympd --help' and it did not show any thing without 'sudo'. I think that help message should show all options without 'sudo'. Help option itself is not listed in 'mympd help'.

5.7.0 shows the help and lists the help option itself.
