Fixed most getColumn() bugs reported in
- Added COLUMN_SIZE (in part to move later columns to right ordinal position). [With workarounds for INFORMATION_SCHEMA.COLUMN bugs.]

- Fixed NUM_PREC_RADIX (was -1 for cases that should be NULL).
- Fixed REMARKS (from '' to NULL).
- Fixed COLUMN_DEF (from '' to NULL).
- Fixed CHARACTER_OCTET_LENGTH (was 4). [With workarounds for (possible) INFORMATION_SCHEMA.COLUMN bugs.]
- Fixed ORDINAL_POSITION (was returning 1 for every column).
- Fixed SCOPE_CATALOG (from '' to NULL).
- Fixed SCOPE_SCHEMA (from '' to NULL).
- Fixed SCOPE_TABLE (from '' to NULL).
- Fixed SOURCE_DATA_TYPE (from VARCHAR to INTEGER.) [With workaround because SMALLINT not implemented yet.]
