plugin Pubsub Hook: first draft: This new plugin allow to attach an external action to a Pubsub event (i.e. notification). Hook can be persitent accross restarts, or temporary (will be deleted on profile disconnection). Only Python files are handled for now. In the future, it may make sense to move hooks in a generic plugin which could be used by ad-hoc commands, messages, pubsub, etc.
