Title: Hierarchical clustering refactoring

I've sticked my nose into your branch.

I've commited a few pep8 and style issues and some typos + merged master into this branch.

I am worried about 2 things:

I get a speed regression on plot_lena_ward_segmentation.py (30s vs 23s before)
and the example plot_feature_agglomeration_vs_univariate_selection.py is broken
because some objects do not respect the philosophy of BaseEstimator see:

http://scikit-learn.org/stable/developers/index.html#instantiation

tell me if you can work on this in the next couple of days during the sprint.
