this change makes it possible to initialize Sequelize with a DSN that contains a password which contains one or more ":" characters, e.q.

```js
const Sequelize = require('sequelize')
const instance = Sequelize('mysql://root:234*%25%26%23%24%5E%40%23%7B%7D::\'.%26%40%40@localhost:3600', {});
```

in this example the MySQL password would be: `234*%&#$^@#{}::'.&@@`

without this change Sequelize attempts to connect to MySQL with a password of `234*%&#$^@#{}` ... this is a truncated password that results in a failed connection.

* Added ids to

* Removed extra added newline.

Also correct the section about promises to sound more nice.

Also `fieldName` and `freezeTableName` is nice features, but not something you need in a getting started guide. It just makes it look more complicated.

I even think that the `pool:` option in "Setting up a connection" should be removed, because who needs that anyways when they are first getting started? I could make new people think that they need it.
