Proposed changes (some stuff still needs to be researched):
- Improve volume level rating (keep track of voice levels?)
- Improve voice age rating (ticks and/or noteID)
- Add settings for selecting voice stealing presets and setting custom
weighted rating values
- Add variables to voice structure for each criteria (ratings get stored
here for statistics)
- Add voice kill log to track what voices got killed and the criteria
ratings of the voice (the reason)

As already reported, such an algorithm needs to take into account the
current position in the volume envelope. The quietest voice might be a
note that has not started climbing the attack slope yet; we don't want
to kill such a note.  The quietest of those voices which are past the
attack phase, instead, might be a good candidate.

BUT (I insist, since Toby put it so clear):

So this becomes:
- Improve volume level rating and limit to notes beyond attack phase (keep track of voice levels?)

And needs in addition:
 - Add rating for notes in attack phase


And what about a little switch for those anyway:
default        // The current algorithm (with improvements)
oldest        // Oldest voice gets killed
quietest    // Quietest voice gets killed
