joblib as optional dependency

[josef...@gmail.com]

Based on the previous joblib thread, I would like to add joblib as
optional dependency, and see how well it works in some of the Monte
Carlo, bootstrap, permutation examples.

I'm thinking of "borrowing", i.e. copying, Alex's code, which looks
pretty much what we would need:

conditional import (try import joblib first, before importing it from sklearn):
https://github.com/agramfort/mne-python/blob/master/mne/parallel.py

and a nice example
https://github.com/agramfort/mne-python/blob/master/mne/stats/permutations.py

Thanks Alex, and I hope as compensation you will get a few more
permutation tests.

help yourself !

it's better if this code comes from a standard stats package.
That will be less maintenance for me :)
