Add loop method to \Zend\View\Helper\PartialLoop

[bfolliot]

Allows to chain setter with rendering, for example :

<?= $this->partialLoop()
    ->setObjectKey('myKey')
    ->loop('myPartial', $myArray) ?>

An alternative could be a 3rd parameter to invoke for the key.

Please add unit tests for the new method. Thanks!

[bfolliot]

All test for the __invoke method work for the loop method, are you sure we need to duplicate the tests?

[froschdesign]

All test for the __invoke method work for the loop method

• New method – new test
• There are different return values.

I'm not sure for the name of methods

Thanks, @bfolliot !
