Congregational Person Statistics to be added to the System-wide Person Statistics

[simon-KAC]

Requesting the 'System-wide Person Statistics' be able to report by Congregation.

Currently the 'Persons->Statistics' menu item displays a table of total people in each Status type. That is really useful. We can paste that data into a spreadsheet to show a pie chart on how many people are connecting compared to core or crowd etc.
I would like to be able to see that breakdown by Congregation.
Each congregation has its own ecosystem. When trying to move people from one Status (eg, connecting) to another (eg, Core) it is helpful to see how each congregation is going with that project.

Perhaps a filter on the 'Persons->Statistics' page could be added?
Thoughts?
