This change does two main things: - element references are recached after next-page results are loaded - any requests initiated before a turbolinks pageload are ignored if they complete after the results are loaded The element reference to the container element is made by attaching a unique data attribute to it: “data-jquery-infinite-pages-container” and setting the value to a unique id for the instance of InfinitePages. Requests are ignored by keeping a queue of timestamps marking when they begin and keeping a timestamp of the last time turbolinks changed the page, invalidating all before that last page-load.
The previous implementation would wait until scrolling stopped to check and potentially load the next page results. This change allows for checks to occur (periodically, at the scrollDelay frequency) so that results can be loaded while scrolling is still happening.
We need to actually call shouldCheck.

In the previous version, the old $container element could still be referenced once a page load occurred. This fixes that problem by passing the old $container element reference to the post-load methods, ensuring a newer reference to the container is not incorrectly updated.
