Choosing number of threads and posts to display per image

With the influx of tag alias/implication threads, I find myself wanting a few more threads per page on the http://danbooru.donmai.us/forum page.

Any way to add this as a quick fix, albert? Right now it's 20, I'd probably set mine to 25 or 30.

I'll change it to 30.

Thanks.

This broke the "last" links in the topic list. Especially noticable for the "Auto-deletion appeal" topic where it links to page 13 when the thread now only has 5 pages.
