Title: scatter_matrix bug

Currently scatter_matrix passes all unmatched keyword arguments to both scatter and line subplots (off-diagonal plots are scatter, diagonal plots are discrete or continuous histograms). I needed to color the points on the scatter plots but could not pass a "c" argument or pandas would try to pass the "c" argument to the line plots and barf. This change scratches my itch and doesn't break backward compatibility.
