[TwigBridge] Added form_twitter_bootstrap_layout.html.twig
clean handling of :: passed to find()

Commands cannot have a double colon in their name (for example, a
command can't be named `foo::bar`). However, one might try to
retrieve a `foo::bar` command from the application like this:

```php
$command = $application->find('foo::bar');
```

The `findAlternatives()` method of the `Application` class fails to
handle these strings when there are commands registered with a name
consisting of at least three parts (e.g. a command is named
`foo:bar:baz`). In this case, an empty string is passed to `strpos()`
causing PHP to raise a warning.

Add an action to show *error* pages in kernel.debug mode

See #7446 for the initial reasoning. In short, add to your `routing_development.yml` file the following

```yaml
_errors:
    resource: "@TwigBundle/Resources/config/routing/errors.xml"
    prefix:   /_error
```

Then you can use `http://localhost/app_dev.php/_error/xxx` to preview the HTML *error* page that the default `ExceptionController` (from `TwigBundle`) would pick for the XXX status code.

You can also use `http://localhost/app_dev.php/_error/xxx.{some_format}` to show error pages for other formats than HTML, most notably `txt`.

Note that the status code will be 500 for all exceptions [that do not implement `HttpExceptionInterface`](https://github.com/symfony/symfony/blob/master/src/Symfony/Component/Debug/Exception/FlattenException.php#L47).

##### Want to test with a custom exception?

~~Folks might want to display (part of) the exception even on error pages and thus need to work with generic (own) exceptions.~~

~~They could write an arbitrary controller and throw their exception there. By default, the `ExceptionController` would be used to handle this, only that it would not show *error* pages in `kernel.debug` mode.~~

~~Thus, a simple public setter to change the `debug` flag after construction could help. Do we want to add that as well?~~

If you want to test error pages with your own exceptions,
* create a subclass of `ExceptionController`
* set the protected `debug` flag to false
* register it as twig.exception_controller in the config
* throw your custom exception from any controller.

That should give you the error page also in `kernel.debug` mode.

##### To-Do
- [x] Update docs
- [x] Add route in symfony/symfony-default

[FrameworkBundle] minor fix

A small fix in the "parse" function of the "ControllerNameParser" Controller.
We should use "!==" instead of "!=" since it's better and faster in this case.

Commands cannot have a double colon in their name (for example, a command can't be named `foo::bar`). However, one might try to retrieve a `foo::bar` command from the application like this:

```php
$command = $application->find('foo::bar');

In a "real" Symfony application, calling `php ./app/console cache::clear` now results in the following error message:

```
  [InvalidArgumentException]
  There are no commands defined in the "cache:" namespace.
  Did you mean this?
      cache
```

This PR partially reverts #12109 because it didn't take into account that many dumps can share a single style tag.
More importantly, this PR enhance dump rendering with some cute JS navigation effects:
- references highlighting on hovering
- moving references toggling

Here is a screenshot (note the yellow background and the fact that `#2` appears after the first `@2`):

See http://yaml.org/spec/1.1/#id858936 specifically the spec about specific data types.

Sample code that exposes the issue:
```php
$yaml = new \Symfony\Component\Yaml\Yaml();

$expected = array('float' => (float) 1);
$test = $yaml->parse($yaml->dump($expected));

if ($expected === $test) {
  print "match!\n";
}
else {
  var_dump($test);
}
```

This will output
```
array(1) {
  'float' =>
  int(1)
}
```
