Blank column names break csvsql

Created by: onyxfish

csvsql -i postgresql examples/realdata/FY09_EDU_Recipients_by_State.csv

Column must be constructed with a non-blank name or assign a non-blank .name before adding to a Table.

Column 10 is blank in sample file.

Unclear if this is best resolved in csvkit, agate, or agate-sql. (Probably the latter.)
