Add "isolated" instance tagging to examples
Add Getting Started section to README, use markdown
Allow single top-level source/destination in manifest
'tags' field not supported in spot instance requests, yet
Add validation "framework", validate manifests

Also some tests for said framework.
Explicitly grab instance credentials when processing manifests

This allows the manifest to work "out-of-the-box" in Ubuntu, where an
older boto version doesn't do this for you.
Look for handlers in hc2000's directory
Add .gitignore for *.py[co] files
Add convenience AWS scripts

These can be used inside running instances to perform specific tasks.
They rely on "automagic" credentials, such as those obtained from the
instance profile's role.
