Updated playback/recording device
Massive revision with changes to how stimuli are selected in SIN_stiminfo, lists are generated in SIN_getPlaylist, all the way down to renaming (and slightly revising) the main player (previously portaudio_adaptiveplay, now player_main). Also small changes to ANL_GUI.fig (CWB was in the midst of adding axes for concurrent plotting, then decided it would be too slow and error prone).
