inotify monitor data directories, to avoid rescanning

[johndrinkwater]

For the current locations of os.path.join( os.path.split( os.path.abspath(__file__))[0], 'sounds', '*.*'), os.path.join( os.path.join(BaseDirectory.xdg_data_home, 'anoise'), '*.*') want to add file update notifications to add new tracks, new track artwork, update now playing trackid (’cause sorting playlist number will adjust)
