Support for DatabaseColumnReference in queries

Example:

        DatabaseTableAlias m = memberships.alias("m");
        DatabaseTableAlias p = persons.alias("p");
        DatabaseTableAlias o = organizations.alias("o");

        List<String> result = m.join(m.column("person_id"), p.column("id"))
                .join(m.column("organization_id"), o.column("id"))
                .whereIn(o.column("name"), Arrays.asList("Army", "Boutique"))
                .whereOptional(p.column("name"), null)
