ModelEditor: Improve export of diagrams

Implemented new menu item "Export Selected Elements" exporting only
selected elements from diagram to image file. The existing menu item
"Export Diagram" exports the whole diagram always. In both cases any
selection will be removed from the diagram before export and restored
afterwards.

Task.number: QTCREATORBUG-16689
