Why `RowGateway` removed update only modified fields feature in zend-db.

And what’s a good solution in `zend-db`, when I just want to update the modified fields.

### Code to reproduce the issue

```php
$row; //Get exists row;
$row->age = 13;
$row->save();

```

#### In ZF1

Will push `"age"` to `modifiedFields`

Execute sql:

```auto
update table_name set age=13 where id=1;

```

#### In zend-db

There is no record modified fields.

Execute sql:

```php
update table_name set age=13, username="xxx", create_time="xxxx" where id=1;

```

Who knows. That’s just too long ago.

This is a feature request and can be implemented as “[RowGateway Feature](https://github.com/zendframework/zend-db/tree/master/src/RowGateway/Feature)”.

A pull request with unit tests is always a help! 😃
