jp9000 717a2538f4 Implement source removal via GUI
- When the remove source tool icon is clicked, it will now remove the
   source from the scene.

 - Fixed a bug where the scene item removal callback would add the scene
   item to the list instead of removing it.

 - Changed AddSourcePopup to AddSourcePopupMenu.  Name actually confused
   me once despite being the writer, so it was clearly a bad name.
