Scroll hook thread polling adjusttment.

Fixed an issue with the scroll hook thread polling.
Users scrolling near the bottom of the page are making upwards of 7-10 requests a second to the site.

Added a small timer using the "poll_interval_mindelay" value to prevent unnecessary polling, one is enough during this minimum time delay.
