Show password field when authentication failed.

- add onAuthenticationFailure() method to prepare
  appropriate UIs.
- set "edit" boolean to true so that users can modify
  password when re-seleting a network.
- keep mStatusText shown for simplicity. It has been hidden
  during "editing" phase, but we don't need to do that any more
- modify Connect button handling so that the button
  hides/appears at appropriate time
- manage visibility state of some fields so that
  we can "reset" the status when authentication failed
- show keyboard again when password field re-appears
