When tallying, cap the expected win rate at 1:1M #57

Cap the expected win rate to 1 in a million when tallying game analytics. This prevents math domain errors here regardless of what the Glicko-2 math functions return.

Effectively replaces #54 (although that could still be committed).

Relates to #45.

To be clear, "here" is the "computation of the prediction_cost metric".

Interesting that that prediction returns values in excess of those bounds. Thanks for the patch :)
