Cut release for 2012-Dec-1

[cwolferh]

We may want to create a Releases github wiki page for this project with links to each release. The first release is pre-tim aka 2012-Dec-1.

I have an initial pass at the release: https://github.com/cwolferh/dev-tools/blob/2012-dec-1-release/releases/2012-dec-1.sh . After some initial testing, it looks like it is working against the classic imagewarehouse / imagefactory setup. Note that this "release script" requires the user to edit 3 environment variables related to imagewarehouse / imagefactory. If this script looks good to other folks and we want to have releases in the dev-tools/release dir, I'll submit a pull request. Note that the release script doesn't really have to live in dev-tools as it is responsible for checking out the relevant branch or tag from dev-tools itself, it just seems like the most convenient place to put it.
