1. Use aws cli command tools
Update the AWS documentation to use the new AWS CLI.

Added MacPorts package installation instructions alongside Homebrew instructions.
Fix retrieving of access keys/secrets after creating new IAM users.
Prompt for a CIDR to allow SSH access from. Allows a default of 0.0.0.0/0, which is all IPs.
Add prompt for secruity group name (defaults to 'wirbelsturm').

Only allow access to the various application specific ports by other EC2 instances in the secruity group.

Add support for VPC (currently commented out as the main project doesn't yet support it).
