Multi-line queries

[andreoss]

Let's allow JdbcSession#sql accept multiple String values, instead of explicitly using String.join

        new JdbcSession(this.source())
                .sql(
                                "CREATE TABLE IF NOT EXISTS foo (",
                                "id INT NOT NULL AUTO_INCREMENT, ",
                                "name VARCHAR(50), ",
                                "PRIMARY KEY (id)",
                                ")"
                )
                .execute();
