yaml support: Update link to pull request
yaml support: Remove the prefix > in data.

The prefix > is used to preserve new lines. It works fine
with previous implementation of Ruby/Yaml, but it doesn
work anymore. When removing this prefix, there may be a
problem with multiple-output from the aws.pl (though I
have never seen such case.)
yaml support: use " for quoting data
support s3fs secrets file format
To be compatible with VPC, remove default group for launching instances. Also add --wait option for spot instances. If you request-spot-instances or describe-spot-instances with the --wait option, "aws" will watch for spot request in "open" state. When they are all gone, "aws" will then watch for instances in the "pending" status. When they are all gone, "aws" will exit.
