Includes the bark/growl system for sharing activity summaries. The growl
agent respects the "activity logging" consent flag used by groups,
defaults to not sharing if that flag is not set, and only shares with
the "bark host" when prompted. (The bark host, in turn, currently only
stores responses for hosted ships.)
Also includes all the groups-side dependencies this has, which it needs
for the chats & groups types. Hard-including those files will save us
some run-around during deploy.
