[Form] Added getValidators() to Form class

Bug fix: no
Feature addition: yes
Backwards compatibility break: no
Symfony2 tests pass: yes

I am working implementing client side validation in a bundle that adds validation rules via a form builder. I am currently unable to pull the validators from the Form class which is making the implementation incredibly difficult.

I noticed that the transformers are currently exposed and based on some feedback I got on IRC I am guessing these weren't exposed simply because no one needed them at the time.

Side note: It would be incredibly helpful to have this in the current branch of symfony. I implemented it on master because it is a new feature, but I would be more than happy to patch it into 2.0 if you would like.

👍

As this is new feature it cannot fit into 2.0 series, but 2.1 is just few clicks ahead, maybe this feature will  fit into  ;)

Yes, I can do that might be later today.
