Noise burst fix RC1

When a panic (crash) occurs during playback, the I2S interface can produce a loud noise burst. This firmware intercepts the system panic handler to "emergency stop" the I2S interface to prevent the noise burst from happening. This firmware also adds an "abort" command to the command interface that can be used to test this feature.
