All versions of ChordBank: Guitar Chords

- Adds full support for our left handed users. Just tap the menu button, and the little hand to switch all chords, scales, and reverse fingerings to left or right handed mode. - Fixes layout for tablets (sorry about that--we are working on a redesigned Tablet experience). THANK YOU for continuing to write in as we refine ChordBank's Android app. Please email us as you're using the app and find problems, or features you'd like to see!
