* Encapsulated existing _pausedMaps access in MapManager.Pause.
Added more unit tests.
* Moved the MapPaused flag from MapManager.Pause to MapComponent.
* Moved the MapPreInit flag from MapManager.Pause to MapComponent.
* Changed visibility so content can't access the flags directly.
* It's not the code that is wrong, it's the tests that are wrong!
* Removed completely obsolete bookkeeping event.
