Random key and chords for practice

[xraydog]

I think to make iReal Pro an ultimate practice aide the addition of a random transposition change after each repeat would be a wonderful ear training device. When this option is chosen a random key change would take effect after each repeat. There could be 2 random options: One having 12 repeats one addressing each key and the other random choosing a key for as many repeats as chosen by the player or infinity
