Title: fix(dao): HSTORE checking like ENUM

This allows user can define HSTORE attribute directly.

define like this
```javascript
var Task = sequelize.define('Task', {
title: Sequelize.STRING,
description: Sequelize.TEXT,
deadline: Sequelize.HSTORE
})
```

instead of
```javascript
deadline: {
type: Sequelize.HSTORE
}
```

I think I have to write a test case to reflect this?
