Automate deploy process

This issue represents the dream that someday we might be able to automatically deploy to all our build targets & platforms without visiting a bunch of websites.

This is an "epic" in ZenHub, i.e. it has many "dependencies"/blockers, that can be easily viewed in ZenHub.

Start by reviewing the ZenHub dependencies and blockers attached to this epic, then map the current deployment process across its build targets and platforms. Done means deployments can be performed automatically for all listed targets without visiting multiple websites.
