changeset 32:42989c2e621b

* Fix crash in spectrogram layer when replacing model
* Change sample player's sample path to a single sample directory.
  This makes it immune to OS path separator differences, and ensures
  it can reject configure calls that try to set a nonexistent directory.
  Reloading play parameters (e.g. sample program) should now work.
* some win32 fixes.
