Title: Add option to ColumnBox to support resetting to parents top margin on new page.

This allows for page title text on the first page that is not repeated
on every page. The default is off, so it is completely backward
compatible. I also added a spec to verify the existing behavior
(which was not previously tested) and a spec to for the new option.
