[4.0.0] CLI parameters now work like MVC parameters

[SidRoberts]

Taking this as an example:

php cli.php greeting morning Sid Roberts

Before:

class GreetingTask extends \Phalcon\Cli\Task
{
    public function morningAction($params)
    {
        echo "Good morning " . $params[0] . " " . $params[1];
    }
}

Now:

class GreetingTask extends \Phalcon\Cli\Task
{
    public function morningAction($firstName, $lastName)
    {
        echo "Good morning " . $firstName . " " . $lastName;
    }
}

This, of course, makes Dispatcher::callActionMethod() redundant.
