PRD-4606 - ProgressMarkerBoxes are not content, so we shall not generate auto-boxes when inside table structures
PRD-4606 - Auto-boxes embedded into a table-structure were not updated properly, causing all sorts of warnings to trigger
PRD-4606 - Adding tests for sequence datasource, as it played up during the table tests
PRD-4606 - Ongoing

- Xml-table-output for golden tests is now iterative, and thus runs faster. It therefore now also tests the same code-path as all other table outputs use.
 - Table export now uses the same clean-paginated-boxes code as the pageable mode, which cuts down on the variability of the report runs and ensures that only cells above a given cut-off point are considered for removal
 - Moved long-run test clause into common code, as I can never remember the actual property name that I should use.
PRD-4606 - Ongoing

- Fixed golden samples, as auto-boxes inside tables were generated with a height of zero
