Lost Pairings

I recently made a transition over from using gzipped pickled Python objects to gzipped json'ed Python dictionaries, and somehow managed to run into an error with the main Rumble object, which was deleted each time it was uploaded to. After that all the uploads that happened had their respective bots pairings deleted. I managed to catch it fairly quickly, but about half the bots lost a good portion of their battles, so it's back to the waiting game again. Fortunately after the changes the server uses less memory, so I can do more aggressive caching and have less accidental out of memory shutdowns =)

I also need to whip up a bot comparisons page to compare versions... this or next week I think.
