Title: [ENH] Permuted OLS: Correct the permutation scheme in haxby example.

The mean image per session and per condition is now considered.
Indeed, if no distinction is made, the observations are not exchangeable
across sessions and the permutation scheme is therefore wrong.

As a result, the example is less striking, but this should be improved with the use of, say, RPBI (upcoming PR).
