Error in widget option documentation for the date field type

[waiting-for-dev]

In the date field type documentation for the master branch, it's said that setting the widget option to single_text causes to display an input with a text type. I read this and I was about to extend it to have the HTML5 date type when I realized that, in fact, single_text option gives already a date type. I don't know if in previous releases it was that way or not.

It's new in Symfony 2.1 (symfony/symfony@6d5ad3b ). We should add a .. version-added:: 2.1 block there and change it.
