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`.
Use the native `currentActions.forEach` instead of the Underscore function. We support only IE9+, which means we can use native Array extra.s
