Frequency transition easing

Experiment to apply the Bezier Controller to WebAudio. This is a spin-off of Ease a dot along a curve. Doesn't work in Safari, unfortunately.

Drag a handle to adjust the curve. The sound will play when the drag ends. The frequency shifts from 220 to 660 Hz, following the hand-crafted Bezier curve.

Improvements

• User input for begin frequency, end frequency and duration.
• Show current frequency graphically (it's now in the console). E.g. on note bar.
• Fix monitoring frequency for several notes played at the same time.
