Adds a few more stats to the game listings

I tried adding a few more stats to the game listings.

I was trying to add timestamps, but something is funky with the data and the dates were all over the place.  I know I've seen this before, but I forgot what the resolution was.  Probably something to do with seconds vs. milliseconds.
Nit.

I think I'd prefer formatting in the template: {{printf "%0.1dk" (div .GoldEarned 1000.0)}}

(and exporting a div function).
