Aaron Lehmann 26c9b58504 Clean up ProgressStatus ...

- Rename to Broadcaster

- Document exported types

- Change Wait function to just wait. Writing a message to the writer and
  adding the writer to the observers list are now handled by separate
  function calls.

- Avoid importing logrus (the condition where it was used should never
  happen, anyway).

- Make writes non-blocking
