Updated Default JQuery Path

The defaut jQuery path should link to the current version of jQuery, which is `1.11.1` and not `1.11.0`. Otherwise, I get the following error when I do a `php app/console assetic:dump`:

    [RuntimeException]                                                                                
    The source file "/var/www/roombook/app/../vendor/jquery/jquery/jquery-1.11.0.js" does not exist.
