The _classes.h header file isn't generated for a project with only a main program

[georgeslabreche]

When only defining a main program without any classes:

<main name = "demo_app">Demo App</main>

Running gsl project.xml generates a demo_app.c file that has a #include "demo_classes.h" but the demo_classes.h isn't generated. Neither are the include/demo.h nor the include/demo_library.h header files generated, which means that the project dependencies are not included.

As a workaround I define a dummy class that gets generated but isn't developed any further:

<class name = "demo_app_dummy" selftest = "0" />
<main name = "demo_app">Demo App</main>
