Feature: Real Time Query Result(s)

[alanjames1987]

Query results should be optionally real time, meaning they will change as the collection changes.

This might introduce some other problems, but I think they can all be solved elegantly.

[alanjames1987]

There should be a realtime method added to all result(s) which is called if that result set changes in any way.

results.realtime(function(results) {
    // results is the new results that have changed
});

I like this way better than #15.

To do this all results would have to retain the query that created them.
