The engine class as the component instance manager is the wrong place to control the play/pause buttons. Instead emit a signal in the Song class and update the buttons in a slot in MainWindow. This fixes problems with GUI/pixmap operations happening outside the GUI thread when exporting a project. Closes #435.
