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`.
You could save rendering the badge at all:

```
{tab.badge > 0 ?
  <span className="badge">{tab.badge}</span> :
  null}
```
