Add awsbox dependency and basic .awsbox.json file
the deploy script from browserid

it makes things easier. just do ./scripts/deploy.js create <name>
awsbox env config files
an aws.json config
default issuer to url.parse(publicUrl).hostname

- allow --shim argument for local testing to use gmail.com as issuer
include aws.json config file in .awsbox.json env
log a warning when using ephemeral cookie secret
Use .awsbox.json instead of adding config files
