GUITHARE DIAGRAMS: LignApp application with two light modules.
Problem: Object browser is empty after opening existing document
Decision:
1) --autoload parameter is added. If it is specified myAutoLoad of CAM_Application is equal to TRUE and all modules are loaded when application is created.
2) LightApp_Application::onStudyOpened() method is modified. aModule->connectToStudy() is called for each module if myAutoLoad is true. This allow updating object browser by each module
