New in 20070514

a "gwave2" version that uses Gtk+-2.0 by way of guile-gnome-platform.
Feature-wise, about the same as the previous release.
I think I've fixed most of the crashes.  Known defects:
  Several dialogs that should have defaults don't.
  The change-waveform-color menu doesn't show the colors, just numbers.
