Urgent Bug Fix

- Removed crash when first sound is played from the pitch pipe view

Changes in 1.1.1

- Rewrote sound code in OpenAL, resulting in smaller app size.
- Tweaked lower octave samples for chromatic view so that they are audible using the iPhone's speakers. Please note that they may sound off when heard through the speakers, but this is a necessary compromise; otherwise they can only be heard through headphones. The samples were generated with the correct frequencies. We will be looking for a better solution for the next update, or adding in an option to switch to the more accurate-sounding sine tones.

ATTENTION: We have identified a bug which causes a crash if the first sound played is from the pitch pipe view. Please use this workaround: play any sound on the chromatic or guitar view before using the pitch pipe view. We sincerely apologise for this and a fix has already been submitted.

- Rewrote sound code in OpenGL, allowing for reduction in app footprint and more flexibility for future updates.
- Replaced samples for last three octave in chromatic view so that tones are audible with iPhone/iPod touch speakers
- Some enhancements to pitch pipe graphics

- Replaced pitch pipe sounds with actual recorded samples
- Corrected octave for F-F pipe
- Revised graphics for pitch pipes

- Fixed incorrectly render button textures

- Added 5 other tunings for guitar tuner

- Added F-F pitch pipe

- Added new pitch pipe view

- Option to set tone playback to stop automatically after 3 seconds.
