Chat revamp, phase 2.

- FeedbackMessage has been subsumed into SystemMessage, which now has three
  modes: INFO, FEEDBACK, or ATTENTION.
- Cleaned up methods for sending those system messages.
  - on the server: sendInfo(), sendFeedback(), sendAttention()
  - on the client: displayInfo(), displayFeedback(), displayAttention().
