Control play/pause buttons in slot of MainWindow via signal in Song class

Browse Source 
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.
