Details:

This is a small update of function 'kmeans'.

It adds the 'display' option, to show a summary of the clustering process.

It stops the iteration when no data point switches group, otherwise it takes
one more iteration to meet the stop conditions, even if nothing changes.

It throws a warning when the process did not converge, e.g. when the iteration
stops for reaching the maximum number of iterations and the error is still
sizeable.

Note: I also posted a patch for patch #9743 silhouette function.
