[Console] fix NullOutput

It should not extend from abstract Output class because than it inherits the useless constructor arguments and applies formatting in write() needlessly.
[Console] the default type value should use the constant in OutputInterface::write
[Console] fix abstract Output class that fasly claims to support guessing of decorated variable.

Also we don't need to typecast to boolean as its already done by the formatter and its his responsibility
[Console] fix phpdoc of Output classes (esp. regarding the new verbosities)

also add missing information
[Console] use inheritdoc for Output classes

[BrowserKit] should not follow redirects if status code is not 30x

Currently, BrowserKit operates incorrectly. It follows "redirect" when `Location` header is present, but having just the header is not enough to perform redirection. [RFC-2616](http://tools.ietf.org/html/rfc2616#section-14.30) precisely says that the redirection should be performed only with `30x` status codes.

This PR fixes the incorrect behaviour of BrowserKit and make it consist with both the RFC document and with other clients, used for example with Behat.

I've found the issue while testing my application with Behat. I was returning `Location` header with `HTTP 201/Created` status code and was surprised that BrowserKit follows the redirection.

This PR is for 2.3 version (master) of Symfony.
