Fix Aseba domain and organization

Created by: stephanemagnenat

Currently throughout the different programs the organization and domains are set inconsistently. These should be used:

QApplication app(argc, argv);
...
app.setOrganizationName("Aseba community");
app.setOrganizationDomain("aseba.io");
app.setApplicationName("XXX");

where XXX can be Studio, Playground, etc.

Note that QCoreApplication provides static methods in case no application object is available.
