Assymetric pairings

Also, a number of values are coming up 0. Will those eventually update when pairings complete, or are not all scores currently tallied (either intentionally or due to a bug)? I know there was talk of dropping ANPP, so maybe that is 0 on purpose, but Vote for XanderCat 12.6 also comes up 0, even though XanderCat 12.6 shows up against PolishedRuby, who XanderCat gets top score against.

Those complex rankings are coming up 0 because they didn't have some battles run against them after the batch rankings was run, and got evicted from cache before their new data was written to disk. I think I'll do a disk dump at the end of each batch processing job, see if that sorts this out.

A lot of these problems are showing up because I put a bit too much 'eventually' into the 'eventually consistent' model.
