Support for three levels of column nullability: NULL, NOT NULL, and the database's configured default.

The default Column configuration (nullable=True) will now generate NULL in the DDL. Previously no specification was emitted and the database default would take effect (usually NULL, but not always).  To explicitly request the database default, configure columns with nullable=None and no specification will be emitted in DDL. Fixes #1243.
