* Initial support for closing maps: * Lots of cleanup functions has been added * TODO: Cameras are only removed when all maps are closed * TODO: Screen leaves traces when the last map is closed * Replaced pre/postMapRemove events with pre/postMapClosed * Fixed a bug in the Toolbar where it didn't properly handle removal of actions from an actiongroup
