Added zbar and audio messages to project.
different naming convention for audio messages
The tutorial screen is working completely. The scanner screen scans and registers the QR Codes and highlights the crosshairs accordingly. The audio player plays and pauses the files based off the scanned codes. The speaker bumps to the level of the audio and the bars start and stop animating based on playback. The pie-looking duration counter fills in accordingly. Changed the animation time on the tutorial to a little faster.
