Provide documented access to the current workarea content

Who would benefit?

Extensions which need to retrieve ALL the current entities from the workarea

What impact would it make?

Access to more of the workarea information

How should it work?

The current data[] array is fixed to the single entity which holds the summary information of the single selected entity for html processing.

Information is already informally available via the appHelper.mainWorkareaView backbone view methods but is undocumented and structured differently to to the standard REST API objects.

Why is it needed?

Allow more comprehensive processing of the whole of the current workarea content.
