Forum Overhaul Fix-'em-up Jamboree

There's no easy way to see titles on individual posts.

This is overall a minor thing, but we've sometimes changed the title of a post to make jokes or for Post Making Contest purposes, so it would be nice if that were brought back.

Can agree that the return of thread titles/titles for individual posts would be good: it also serves a very nice function in mafia games in that if you're paging back you can immediately see what day's conversation you're looking at at a glance.
