stats: this makes some fixes to AverageStat and AverageVector.
Also, make Formulas work on AverageVector. First, Stat::Average (and thus Stats::AverageVector) was broken when coming out of a checkpoint and on resets, this fixes that. Formulas also didn't work with AverageVector, but added support for that.
