more stuff broke

Well, I fixed the aforementioned problems a while back. I did not repopulate the database with the missing information, and I think another similar outage happened again since, but there are only a few days of missing data. I think it is negligible for the most part.

Anyway, yesterday or so stuff broke again and my cron tasks ceased to work. rondb also broke for even more mysterious reasons and I can't figure out why (I haven't touched it in about a year). I fixed the ranking.pl frontend though. By request I need to add something that will allow you to search for games where somebody got +-0.
