Deployments page

First go at the deployments page. I'm looking to finish off this feature by tomorrow. Especially I want feedback on the `dangerouslySetInnerHTML` attribute and the ownership of the two functions: `formatCurrentActions` and `formatAffectedApps`.
A more detailed description might be useful here. "Destroy deployment X? Destroying this deployment will start a new deployment to revert the affected app to its previous version."
