Mobile specific header labels for Tables when in mobile view

[CarlosNZ]

Part of Epic #1548

When the tables are collapsed for Mobile, they look okay, but without header labels it's very difficult to make sense of what each bit of information is referring to, e.g.:

I think we should make a utility component called "TableHeaderLabel", and we wrap each Table.Cell contents in it. Then, in that component we determine if we're in mobile or not (using #1568 ) and if so, pre-pend the "header" label to it. And if not, just return the children unmodified.

We probably don't want this for all table cells though, so it should have a "disabled" prop that can be dynamically applied (for Data Views), or we just don't wrap it for static ones (such as the "Status" label on the Application List)
