function oa_archive_trigger_flag in Open Atrium Archive 7.2

Helper function for flag and unflag hooks.

We need to archive/unarchive child content when archiving a Space or Section. We handle unarchiving parents who had child content that was already archived by storing a list of those nodes in a variable.
