annotate widgets/PaneStack.h @ 123:842bf484ee15

* Add Hz tuning dial to sample player plugin.  Need to figure out the best
  way to get this passed through from the main program's configuration.
* Add ConfigFile class to deal with configuration load/save
* Add an organ sample (it's a bit big, though)
