Now it seems it's impossible to import empty string by csvsql. Empty strings converting in NULLs.
Though in csvkit/typeinference.py there's comment for normalize_column_type()

```
NAs and missing values are converted to empty strings. Empty strings are converted to nulls.
```

In fact everything converted in NULLs.
Personally I would prefer to import empty strings as empty string; "na", "n/a", etc as NULLs.

But actually it doesn't matter. There should be a way to import empty strings.
