Bug notes
There seems to be a "race condition" where pageload_servertime is set to something *before* the creation date of the last reply
that is actually included in that page load. This can result in a reply that's already on the page to be loaded (duped)
when the user makes a reply. (Probably not a "true" race condition. More likely the pageload time is set, then the rest of the
page load including the api call to fetch posts on the page takes several seconds, and someone happened to make a post
right between those two events. This is more likely for a busy forum, so we should handle this.)
Probably will need to add something to the thread display to handle this somehow, or pass in a list of all nodes on the page
and exclude them.
**UPDATE:**
Added data-node-publishdate to the <li > tags for the posts, and added JS to go through them
and pass in the max(publishdate[], timestamp). So this *shouldn't* happen anymore.
