azure: try fresh deploy.sh

Try regenerating a new default deploy.sh using:
    azure site deploymentscript --node

The old one caused problems because I re-ordered
things without understanding what Kudu was doing,
fully.  The bower install is now part of the npm
install process, which means this shoudn't really
be necessary.
