Allows to start the scene with custom arguments within the editor

fixes #7346

Path from the current scene isn't added too the argumens anymore by default and needs to be added throug the custom arguments, with $scene. Matches the behaviour of the executable without any arguments.
Custom Arguments are read from editor/main_run_args
