Crystal Ball 0.3

First release.

• Detect a chord by ear — press, strum, and it names the chord and draws how to fret it.
• Runner-up chords one tap away, and other voicings of the same chord up the neck.
• Capo-aware shapes, with the choice of naming the chord you hear or the shape you play.
• Song sheets — capture parts chord by chord, reorder and rename them, fix a chord by hand, and share the finished sheet.
• Chord dictionary, themes, keep-screen-on, and backup/restore for songs.
