[AstroPy] astroquery.vizier.Vizier.get_catalogs doesn't fetch more than 50 rows

[Adam Ginsburg]

Sam & I communicated off the mailing list; he determined that
Vizier.ROW_LIMIT supercedes the '-out.max' keyword.

The other issue is likely a problem with the pip version of
astroquery, which means we need to make a new release.
