[pymvpa] every permutation returning the same value

[Ben Acland]

Figured it out... you'll notice that the classifiers are using the default sample attribute, "targets," but I'm permuting "sub_group." Since I set "targets" to the same values as "sub_group," swapping out every reference to sub_group after that to 'targets' seems to have done the trick.
