Rename PurpleContact to PurpleMetaContact.
Review Request #1770 — Created Sept. 16, 2022 and submitted — Latest diff uploaded
This is to help facilitate the new blist api that's still being designed but we wanted to use this name for an object. A later review request will rename contact.[ch] which was avoided for now as it would make the diff harder to read.
Ran and verified that contacts showed up.
