File size: 71107 byte(s)
* code refactoring: created a PropEdit class for property editor
  windows, moved Table class from mainwindow to paramedit
* minor gui tweaks: made note entry fields a bit wider, set a minimum
  width for scales
* bug fix: avoid stale information in the instrument properties window
  when a new file is loaded or the instrument is removed
