seaborn styles renamed#

Matplotlib currently ships many style files inspired from the seaborn library ("seaborn", "seaborn-bright", "seaborn-colorblind", etc.) but they have gone out of sync with the library itself since the release of seaborn 0.9. To prevent confusion, the style files have been renamed "seaborn0.8", "seaborn0.8-bright", "seaborn0.8-colorblind", etc. Users are encouraged to directly use seaborn to access the up-to-date styles.
