Introduce class that represents a container for widgets that are to be shown when a file is opened. The widgets depend on the type of file that is opened. For example, a TileSetFileView will initialize widgets that allow the user to view the TileSet and edit its properties. When a tileset file is opened, a properties box and the tileset view itself may be shown.
