Create tag for all stable releases when they are phased out.

[Ali-Khatami]

With the latest release of 1.1.1 and a 1.2-wip branch already being worked on it seems like moving forward a tag should be created for all stable releases when they are phased out. This way developers who have yet to upgrade or feel they can not upgrade (for what ever reason) will be able to review docs and can find their stable version. Also, it will provide better history, bug tracking, etc as the framework evolves.

Ideally we would have a tag for each stable release <major>.<minor>.<patch>, but if that becomes obnoxious it would be nice to at least have a tag for <major>.<minor>.<last_patch>

The build script does have the --release flag which will create a tag based on the version. I think we just need to make sure to do that when releasing a new version.

It probably wouldn't be bad to go back and tag the previous releases as well.
