bug: Fix copying of page assets during the bake. * The `Assetor` wasn't setting the "used assets" flag on the correct object. (I wonder why Python didn't complain about that) * The baker wasn't looking at the right input filename.

#!/bin/sh

CUR_DIR="$( cd "$( dirname "$0" )" && pwd )"
CHEF=${CUR_DIR}/../bin/chef
OUT_DIR=${CUR_DIR}/../piecrust/resources/messages
ROOT_DIR=${CUR_DIR}/messages

$CHEF --root=$ROOT_DIR bake -o $OUT_DIR
rm ${OUT_DIR}/index.html
