SocketConnection parser cast + RoomChatHandler arg-order fix

- SocketConnection.processMessage() did 'new events[0].parserClass()'
  where parserClass is typed as 'Function' on IMessageEvent (no
  construct signature). Cast to 'new () => IMessageParser' at the
  call site so the spawned instance is type-correct downstream.
- RoomChatHandler dispatched RoomSessionChatEvent with the args in
  the wrong order: '[]' (intended as the 'links' array) was landing
  in the 'chatColours' string slot. Swap to '"", []' so links go
  to position 8 and chatColours stays a string.
