Title: Take aws keys from environment

Modified shim.pl to take the values of the EC2_ACCESS_KEY and EC2_SECRET_KEY environment variables if they are not provided in the sketch parameters.

Also fixed some cosmetic output and added a second example json file, as used in the Design Center webinar demo.
