Battlebots Elo

I am no longer maintaining a Battlebots Elo scoring system, for a few reasons.

• The code wasn't very good.
• There are many other people doing the same thing with a longer lookback period. My personal favorite is the work of IAmTotallyNotSatan.
• This was an exercise for me to see how Elo's might work for Battlebots, and more seasons won't prove or disprove it any more than has been done already.

Thanks for the kind words over the past few years of doing it.
