show notes in the current selection for harmonization

[bwl21]

Request

when creating a harmony voice it would be nice if we could see the notes at a given point in time rep. in a selection

Solution

1. initial:

   • Determine the notes in harpnote player and report them as info in console.
   • remove display of mode in status line to make room for further enhancement

2. advanced: integrate a harmonizer which shows the note and matching harmonies

it is somehow implemented but it also shows pitch of breaks ...
