scipy core patch

I suggest backing out the patch, removing the changes to

    > "resize", and putting the modified version back.

I've been working on this in my local tree and need just a few more
modifications before committing. I already made this change, as well
as making all three packages supported. There are additional issues
to fix, eg the scipy.fftpack import is broken if only scipy core is
installed and not the full scipy, and Robert has been helping me a bit
with these.
