Summary: FFTW3 interface for pd-0.41-4

Initial Comment:
The attached patch implements the necessary functionality to emulate the mayer_fft with FFTW3. It's a strange approach and not ultimately efficient, but it's better than the plain mayer_fft in any case.

Took it -- but probably won't test it - caveat emptor

  info->in = (fftwf_complex*) fftwf_malloc(sizeof(fftw_complex) * n);
  info->out = (fftwf_complex*) fftwf_malloc(sizeof(fftw_complex) * n);

shouldn't this be fftwf_malloc(sizeof(fftwf_complex) *n)?  I think you
allocating for doubles instead of floats.
