- [x] Fix the problem with wrapping wide lines (https://github.com/symfony/symfony/pull/20951#issuecomment-292201983)
I got motivated by recent PR https://github.com/symfony/symfony/pull/20951 and redesigned the exception page even more.
Compare before: 
with after: 
(Ignore the the "sf" toolbar icon in the middle of the page. This is how Firefox does full-page screenshots.)
The most noticeable changes:
- removed double line spacing (it just does not feel natural)
- file context increased from 3 to 10 lines (it helps me to better orientate in the code)
- added horizontal scrollbar for the cases when the code is wider
- the highlighted line color is more saturated in order to be noticed easily

[TwigBundle] Add Content-Type header for exception response

This PR comes after I was looking to customize the way exceptions are served for a JSON API (grabbed the info at http://symfony.com/doc/current/controller/error_pages.html#overriding-the-default-exceptioncontroller).
I noticed that even when changing the request format to 'json' so that the right json.twig template is served:
```php
// in my override of the ExceptionController
public function showAction(Request $request, FlattenException $exception, DebugLoggerInterface $logger = null)
{
$request->setRequestFormat('json');
return parent::showAction($request, $exception, $logger);
}
```
the response Content-Type header was still 'text/html'.
By now, the response Content-Type should be corresponding to the given request format.
I also feel there's some room for improvement with the general "displaying error for a JSON API" chapter as it feels strange that there's no configuration option to just say "serve me anything as json", but that's another issue.
