Rheia: fix bug where remove linked in moderation view does not really remove link in db
Hyperion: definitively rename getLinked to fetch
Hyperion: fetch now uses cache, to avoid referencing with two different models the same entity. Unless explicitly specified (GameService.getItem(), GameService.getEvent()) for serialization reasons
Hyperion: use cache to resolve player characters
Hyperion: move connetedList from web/middle to service/player: will allow dev access reuse after server restart
Atlas: allow automatic reconnection when server restarts
Atlas: some small fixes
