Change to Qt5 conding conventions

Data structure changes:

 - Structogram is no longer just a scope, because it needs to store
   metadata
 - All structures now use QString instead of std::string, to
   integrate better in the Qt framework

New code:

  - MainWindow ui code, building layout
  - MetadataDialog to change the metadata stored in the Structogram
  - Painter is a widget (still unimplemented) to show the structogram
    on the GUI
