Behavorial Changes:

* Confirmation dialog for remove has been removed.
* Remove button is disabled if the currently selected status is the active
  status. Previously this scenario was silently ignored after confirmation.

Errata:

It is possible to open multiple modify windows for a status. Previously the
editor was reaching into the manager and controlling this pointer. I was going
to fix this, but the editor isn't a widget yet and I don't like doing duplicate
work.

Basically tried everything I could think of with editing and selecting and so on.
