Expanding Bay Area definition to match Census Bureau, including Santa Cruz and San Benito Counties 

An update which was made to Template:SF Bay Area brought to my attention that the Census Bureau includes Santa Cruz and San Benito Counties in its definition of the contiguous metro area of the San Francisco Bay Area.  See Template talk:SF Bay Area.  The Census Bureau is WP's preferred reference when available.  For consistency, I'm going to add those counties' airports to this page and the Bay Area airports navbox.
