[IBL] ratings updates

[Sean Sweda]

I'm not going to have much time to work on the cards between now and Sunday night, so this probably the final update before we start drafting by lists.

I'm in the process of overhauling the defensive range ratings to use the Inside Edge fielding data on FanGraphs.  This data is much better than BIS ZR/OOZ because it breaks plays down into degrees of difficulty and includes a denominator (chances) for everything.  I've worked out all the issues with using the new data, but I still need to do some work before the ratings are complete.  I figured that estimates were better than nothing so I've uploaded a file that has the players broken down into categories: 

great = likely range rating of A/B
good = likely range rating of B/C/D/E
average = likely range rating of E/F/G
poor = likely range rating of G/H/I/J
awful = likely range rating of J/K

When I've completed the work I'll post a full write-up on the blog.
