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.
Workaround boto in latest Ubuntu (13.04)

The version used there (boto 2.3) predates IAM instance profiles, which
come as a JSON file. Older boto versions attempt to split that into
lines.

Falling back to plain urllib2. We will want to add this, anyway, to
support more URLs than just S3. (Not implemented here, though)
Fix manifest validation: must use indirection on validator
Grab content from URL, not URL itself...

Stupid bug!
Make run-command-notify work on Amazon Linux

Current Amazon Linux (2013.03) is using python 2.6, which doesn't
support subprocess.check_output.
