Removed col classes from LocationTab action buttons.

Also did a tiny bit of code cleanup.
Fixed the generated LocationTab additionalFields links.

They still don't trigger the correct collapse/expand toggling though.
Injecting headers in all cells in the LocationTab cells.

Toggling between global header and local headers when shifting from md and lg to xs and sm.
Also marking the three types of rows (header, actionButtons and additionalFields) up more robust,
so table rows that are neither does not get marked, only transformed into divs.
