Subject: [PATCH] blueprint: add change object for blueprints

Add a struct to store changes made to a blueprint. Each change contains
a commit which is a hex string based off of an sha1 hash, a message
describing the change, a revision which will usually be null, a
timestamp, and the blueprint at the time of the change.
