Fixed IAM Names
removed the name_prefix parameter from aws_iam_role and
aws_iam_role_policy. They have caused nothing but trouble since you
can't pass long string in as names, we keep running into AWS errors
trying to deploy aws_iam_role and aws_iam_role_policy resources with
names that are human readable, and frankly never use the human readable
names.
Also, updated the README format to be more readable, as well as other tf
file formating for readability, no other changes.
