EUCA-7930
At one time I put a hack in to optionally disable the page redraw when help was flipped back to the content page, because the wizard would lose all it's user input. Now it seems this is required of the landing pages too, since the rework. Hardcoded to never redraw, and checked behavior in landing pages, wizards and dialogs. All appear to preserve input data now. Also removed the 8px margin on the vertical sides of .dataTables_wrapper, as it left black bars on the sides when returning from help. The redraw hid that before.
