Automatic Tagged Release Deployments

To support better CI development flows, if a tagged release is created in Github (or other VC system) it would be great if this can then auto-deploy. For example I might have the following setup:

1. dev.website.com = dev branch = auto-deploy when pushed

2. staging.website.com = staging branch = auto-deploy when pushed

3. website.com = v1.0.1 = auto-deploy when created
