Control Center App export change (default) mainline to location latest activity (branch or mainline) and add fields

When having a lot of apps, the export function should make more sense.

the export app function in the control center at present exports by default only the mainline activity. Please change this to wherever the latest activity takes place, so branch or mainline.

Also also add the following fields:

1. Technical contact
2. Last commit by
3. branchname (mainline or branch)
