* Fix #1628781 changes to layer visibility and mute should use a command
* Also use a command for changes to layer playback pan, gain, plugin settings
* Refactor PlayParameterRepository to remove dependency on audioio from base
* Fix failure to save play parameters for main model in session file

 #include <QTextStream>
