Blips v1.6 - Scale and key fully supported

Scale and key values can be changed.
Values are persistent.
Changes reflect immediately.

TODO:
1.7   Fix volume for bb6-g6 (Audacity)
         Effect amplify track and set peak to -10db
         Trim so transient is at 0:0:00 time and end track is 1.5 seconds
         Select whole track and effect "Fade out"

1.8   Fix load
       1 My guess is load is setting the loaded values, then shared preferences
         is resetting them to the last saved value it stored (different than
         load's values.)

       2 We also still need to reflect changes immediately, not on refresh

1.9   Add tempo slider
         If you add a slider and a "valueChanged()" callback, I'll implement it

2.0   Add graphics
         This is between you and the graphics guy, but I'd like some input.

I think we should be at 1.8 or 1.9 for the Alpha Release demo. Any input?
