When the classes in wave.py opened files themselves, their .close() methods
didn't bother to close the files. This caused the new test_wave test to fail
under Windows, as Windows won't let you delete a file that's open. Fixed
that by ensuring the wave read & write classes' .close() and __del__ methods
close files that were opened by their constructors.
