plugin XEP-0280: priority and "sent" fixes: - carbon prioriy must be bigger than ones of encryption plugins, because the carbon copied messages must be unwrapped to be decrypted, this patch fixes it - "sent" carbon elements was only stored and notified to frontends, it is now unwrapped and injected in normal traffic, this way other plugin can manage it, in particular encrypted elements can be decrypted
