Bug 23767: Total children only if parents not visible

Bug 23767: Total children only if parents not visible

This patch changes the way to calculate the footer. It adds the budget and parent ids to the cell
as custom data elements. When totaling we grab a list of all the rows we are showing - if a
row has a parent and the parent is showing then we skip adding its value to the total.

As the function is used on both acqui-home and aqbudgets I adjusted both templates

To test:
1 - Follow the test plan on previous patch
2 - Try filtering the table so you see only the child funds
3 - Confirm the totals show the child alone when it is visible
4 - Confirm the child total is excluded when the parent is visible
