Executing a function to make a get request while simultaneously triggering a scroll event within the executed scroll event is probably not the best idea.

This still needs work, there should probably be something else used to check for updates, such as an event where page has focus or something else that doesn't get called so many times, preferably something that reduces the timer instead.

This is just a quick fix to stop all the lag on threads when scrolling near the bottom.

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.

This reverts commit e9226dba46.

check if viewing a thread or viewing a board page when updating a thread so new posts do not appear at bottom of page while viewing threads list not sure if this was because of an outdated template but I thought I should point out this as it may affect html templates no matter the code as the banner code is the only code that checks where the user currently is.
