[Numpy-discussion] defmatrix move and unpickling of old data

Just to let you know, I now fixed the problem using:

import sys
import numpy
sys.modules['numpy.core.defmatrix'] = numpy.matrixlib.defmatrix

The key is that the statement "import numpy.core.defmatrix" needs to work
for unpickling to succeed, and just renaming things isn't enough.
