[lively-kernel] More Sounds

[Bert Freudenberg]

Very nice indeed!

The PluckedSound, at least, sounds better than its Squeak predecessor now. I guess we should port back your improvements :) I tried commenting out the Squeak primitive code, and found that with current CPU speeds, it is not needed anymore. On my machine the synthesis, even if interpreted, uses only about 1 % of CPU time per voice.

One feature missing from the Lively keyboard (that the Squeak one had) is sustaining a note as long as a key is pressed.  And loading MIDI files can't be that far off, right? Only attaching an actual keyboard might proof impractical ...

Also I added a line of interpolation to banish the noise in PluckedSounds - they're really nice now.  I also refactored everything so that Envelopes are free of streaming state and thus can be shared among notes.
