Form request obj tip

I think we should modify this or maybe not include i - here's why:

• In reality, since forms elements are always namespaced, you'd actually need to use the form's "name" to get at the entire submitted array (not directly at a single field)

  $allTheData = $request->request->get('some_prefix_product');
  

• I think we should say quite directly that this is how you access the raw POST data

• We should warn against using this - the data is on $form->getData(). I see a lot of new people call $form->bindRequest($request), then immediately grab and use the raw POST data - they don't quite understand still what's going on.

Thoughts?

@weaverryan I'm assuming this issue (your third bullet point) primarily seen with the original Symfony instead of Symfony2? I'm not sure that I've even seen mention of this method of getting POST values in the docs, so I'm surprised that new users would experience that confusion otherwise.

Made another commit with a bit more of a warning. I personally prefer erring on the side of too much information instead of too little... but... if you think it should be scrapped, my feelings won't be hurt. :)

Great! I think this is a good addition indeed :)

There is a display error with this update.
On the book page (http://symfony.com/doc/current/book/forms.html#using-a-form-without-a-class), the php code in the tip is not display

Weird, I'll add a commit to add some whitespace to see if that fixes it?
