logic: initially parse source on message thread and add more StatusBar messages

This change puts the initial project loading into a MessageLoadProject so that the UI thread is still responding.
Also the StatusBar is now responding to more Messages and it's MessageListeners get added to the MessageQueue in
front of other listeners so that the StatusBar UI can announce actions.
