running centroid, ward, and median with result from pdist #15

These algorithms operate on dissimilarity matrices as long as they are
Euclidean. The centroid, ward, and median linkage functions should be
modified to support this feature.

+1. This would be great, as people coming from matlab or R would expect this 
feature. In my particular case (porting to python some matlab code), this is a 
pretty large roadblock, as I can't use raw observations.

I just wanted to add that someone opened a ticket against scipy 
(http://projects.scipy.org/scipy/ticket/1272) for this same issue a few months 
ago.
Cheers,
