Subject: [PATCH] Add packer builder for raw images

This builder will build images, in the same manner as other builders,
but with qemu as the "cloud provider."  Right now these are for (large)
raw images, but this could probably be easily evolved into supporting
qcow2.

 This will build AMI images in the us-east AWS region (additional region support to follow).
 
 You may limit which images build by adding the `-only=` flag to Packer.

 There is a helper script to aid in seeding built AMI's to all other AWS regions.
