Title: Should we use PyFFTW instead of PyFFTW3 for astropy.nddata.convolution?

This is a question for @keflavich - I had not realized that there were two distinct Python wrappers for FFTW - http://pypi.python.org/pypi/pyFFTW/0.8.2 and http://pypi.python.org/pypi/PyFFTW3/0.2.1 - and I think that PyFFTW3 doesn't support Python 3 (and there haven't been any recent releases). Is there a reason why PyFFTW3 was used, or could we equally well switch over to using PyFFTW, which I *think* may support Python 3?
