Title: Cache option

Now NGScroller has a cache option!

Here is demo. Try to load ~100 items and then scroll back through whole scope (for both cases; data-recieving delay simulation illustrates the difference).

By default cache is disabled. To enable cache there is a syntax:
```html

```

Cache mechanism is very simple. We memorize datasource.get result items with indexes (without any bindings; pure objects only) and then replace datasource.get(start, length, callback) call to it's callback call. And callback recieves cached items.
