Reword two confusing mainframe hints

- DecodeMessage::PLAYER_3 ("locked up bash files should be removed to
  lock it up") was awkward and unclear about what it meant.
- The private-communication hint said "contact each other privately",
  which read as any one private message rather than the actual
  requirement of messaging every other agent privately.
