Title: Create a ssh_config file if not exists

When `ec2ssh init` is executed without ~/.ssh/config, Errno::ENOENT is raised, so some error handling is needed.
Creating a blank ssh_config file at the beginning of `ec2ssh init` is a reasonable solution, I think. This is convenient when you run `ec2ssh` on newly created EC2 instances, for example.
