Move stat descriptions out of the config.

This lists stat descriptions in an Erlang term file to avoid abusing the config system. Uses a file in CouchDB's priv directory that is a list of three-tuple terms.

Fixes COUCHDB-396

Makes the stats calculated over a moving window isntead of calculated for non-overlapping timeframes. This should make trend monitoring more robust.

Thanks once again to Bob Dionne for double checking this.
