Fix #2002 Tag::linkTo() to allow the addition of query string parameters

[dreamsxin]

See #2002

echo Phalcon\Tag::linkTo(array('signup/register', 'Register Here!', 'query' => array('a' => 1, 'b' => 2)))

<a href="/signup/register?a=1&b2">Register Here!</a>

[phalcon]

I think those query arguments must be passed to the url service: https://github.com/phalcon/cphalcon/blob/master/ext/mvc/url.c#L269

[dreamsxin]

You are right
