Send back target path for easier using navigo

[martonx]

When we catch a navigate event, and we want to do ajax call based on the catched url, and we use just some general route like /user/:action/:id in our rooter, then we need to know what was the originally catched url, without rebuild the original url from response parameters, query strings or without any hacky other solutions). I know this is not the most elegant way, but it doesn't break anything and better then nothing. In v5 navigo should send back an object with { params, query, targetPath } instead of 3 arguments.

The router already have _lastRouteResolved property that contains the latest resolved URL. I just made it available as a public method router.lastRouteResolved(). Here's a test that covers it:

describe('when we have a complex route matching', function () {
  it('should access easily the matched URL', function () {
    var handler = sinon.spy();

    router = new Navigo();
    router.on('/user/:action/:id', handler);

    router.navigate('/user/answer/42').resolve();

    expect(handler)
      .to.be.calledOnce
      .and.be.calledWith({
        action: 'answer',
        id: '42'
      }, '');
    expect(router.lastRouteResolved()).to.deep.equal({
      url: '/user/answer/42',
      query: ''
    });
  });
});

Use 4.5.0. lastRouteResolved is available there.
