Make an inventory of the UI components that are used in Essentials but are not yet in the Hippo theme

Current Hippo theme can be found here: http://onehippo.github.io/hippo-theme-demo/

On top of the existing components, also make sure to mention the near-future expected components:

1) global indicator that the project needs to be rebuilt
2) global indicator that some content beans need to be regenerated
3) widget to make response messages better visible, including history

Tobias: Marijan to provide a list of visual widgets of components. That list should be reviewed Oscar to make sure they get included in the Hippo theme or at least styled by Anton. (Taken from ESSENTIALS-209)
