fixed reverse chronological ordering in a pair of FTs clogging the pipeline; added ActivityPub to project; new apps.ap for WebFinger, Actor, Outbox views; apps.lyric.models now contains ap_public_key, ap_private_key fields + ensure_keypair(); new apps.lyric migration accordingly; new in drama.models are to_activity() w. JoinGate, SelectRole, Create compat. & None verb support; new core.urls for /.well-known/webfinger + /ap/ included; cryptography installed, added to reqs.txt; 24 new green UTs & ITs; in sum, project is now read-only ActivityPub node
