LibreTime: restore settings
Symptom: LibreTime not playing, cannot upload, "Dashboard, Tracks" screen shows twirly icon, "Settings, Status" screen is blank.
Resolution (to be confirmed)
Run the /vagrant/install script. At every prompt select not to make changes. May need to re-establish PostgreSQL credentials on first launch of WebUI (http://airtime.soundfm.ca:80/ ) - this may be avoidable byrestoring /etc/airtime/airtime.conf.bak (created by install script)
(Re)start the airtime* services (used '/usr/local/bin/doairtime start')
If Playout is not advancing to next track, run 'doairtime restart'
