add a namedForm() method in FormTrait

I do prefer using the namedForm builder.

Just add the `$this['form.factory']->createNamedBuilder(...)` in `Silex\Application\FormTrait`:

```php
    /**
     * Creates and returns a named form builder instance.
     *
     * @param string                   $name
     * @param mixed                    $data    The initial data for the form
     * @param array                    $options Options for the form
     * @param string|FormTypeInterface $type    Type of the form
     *
     * @return \Symfony\Component\Form\FormBuilder
     */
    public function namedForm($name, $data = null, array $options = array(), $type = null)
    {
        if (null === $type) {
            // BC with Symfony < 2.8
            $type = class_exists('Symfony\Component\Form\Extension\Core\Type\RangeType') ? 'Symfony\Component\Form\Extension\Core\Type\FormType' : 'form';
        }

        return $this['form.factory']->createNamedBuilder($name, $type, $data, $options);
    }
```

Added support for callables in CallbackResolver

Added the ability for the callback resolver to support any callable instead
of just the object and method callable type.

An alternate implementation to this would be to update the CallbackResolver to use an interface, then keep the old CallbackResolver as is and just add a new implementation that you can change if you'd like. I'd probably prefer to do the interface, but depends on what people think.

This fixes #1327

Remove slash from FallbackResource

Apache config is not my thing, so this might not be correct. However, what I can tell is that it does not work with the slash for me, and that it does without the slash.

Address bc changes from Symfony 2.8 to Symfony 3

removed support for Symfony 2.7 in Silex 2.0

As 2.8 is a LTS and compatible with 3.0, it's going to be much easier to maintain both the code and the documentation for Silex 2.0 if we drop support for Symfony 2.7.

s/middlewares/middleware

Feel free to discard this PR,
but reading 'Middlewares' with an 's' feels jarring to me,
I never saw it written this way before.

For uses without the 's' see :
http://english.stackexchange.com/questions/257120/middleware-vs-middlewares
https://en.wikipedia.org/wiki/Middleware
http://expressjs.com/guide/using-middleware.html

I did find uses of 'middlewares' in these pages, so, again, feel free to discard :
http://guides.rubyonrails.org/rails_on_rack.html
https://blog.engineyard.com/2015/understanding-rack-apps-and-middleware

But for example it appears just twice with an 's' in this stack overflow page, and many more times without the 's' :

Add support for the Guard component to the SecurityServiceProvider

| Q             | A

| Bug fix?      | no
| New feature?  | yes
| BC breaks?    | no
| Deprecations? | no
| Tests pass?   | yes
| Fixed tickets | #1260
| License       | MIT
| Doc PR        | included

Services configuration are extracted from the SecurityBundle [`guard.xml`](https://github.com/symfony/symfony/blob/3.0/src/Symfony/Bundle/SecurityBundle/Resources/config/guard.xml) and [`GuardAuthenticationFactory`](https://github.com/symfony/symfony/blob/3.0/src/Symfony/Bundle/SecurityBundle/DependencyInjection/Security/Factory/GuardAuthenticationFactory.php)

Usage is quite simple, the `guard` type can be configured in the firewall like other ones.

```php
$app['app.authenticator'] = function ($app) {
    return new Authenticator();
};

$app->register(new Silex\Provider\SecurityServiceProvider(), [
    'security.firewalls' => [
        'main' => [
            'pattern' => '^/admin',
            'guard' => [
                'authenticators' => [
                    'app.authenticator'
                ]
            ]
        ]
    ]
]);

Allow use of all the RequestMatcher parameters by providing an array

Provider: Silex\Provider\SecurityServiceProvider
Little patch to make full use of the `RequestMatcher` in `$app['security.access_rules']`

```php
    $app['security.access_rules'] = [
        [[
            'host' => 'symfony.com',
            'ips' => '192.168.0.1',
