[committee] Hantale on Sprocket/Winadmin

[Sam Moore]

I've added Ryan Hall to these groups, because it is easier than trying 
to find the policy on our website*. If anyone objects, feel free to 
remove him pending further discussion.

* The sprocket policy so far has just been for me to add most** people on 
winadmin to sprocket as well.

**
    "We should just merge it with winadmin!"
    "But security!"
    "Kerberos!"
    "OK, get back to me when that's done"
