Feature request for Infinite scrolling

[ggrillone]

I've been working on implementing the infinite scrolling functionality of this addon, and it seriously rocks!

I came across a situation though that I feel might be a good improvement for this addon.

My scenario is that I am using infinite scrolling for a grid view in my application and this grid also has sorting capabilities. When I sort however, it ends up re-rendering everything and the page state of the pagedArray is lost so it is reset to 1. So what I ended up doing is maintaining a separate property to track the "current page". I thought if I passed in this value to the page parameter option that it could auto-load to that page, but that doesn't seem to be the case, i.e.:

var currentPage = this.get('currentPage'),
      perPageParam = this.get('perPageParam');

this.set('infiniteScrollObject', pagedArray('models', {
  infinite: 'unpaged',
  page: currentPage,
  perPage: perPageParam
}));

For now I just created a basic for loop to call the loadNextPage() function X number of times depending on the currentPage value, but it would be useful if setting page during initializing would load the other infinite scroll "pages".
