Document working demos/not working

1. Forgive me if I set up foam incorrectly but I spent quite a few hours on it now. To me it seems only the calculators and the Phone catalog actually work (and some other exceptions, like the hello world)
I would intuitively say that 80% dont work. Also if I build the acalc, the build output doesn't work either ("Unknown Model: foam.i18n.MessagesInjector in GlobalController")
2. Maybe I also did the Todoapp tutorial wrong, but beginning with the DAO stage the steps dont do anything for me (changes dont persist to localstorage)
http://foam-framework.github.io/foam/tutorial/todo/4-dao/
3. There is a foam2 repo in your organization, this strongly implies that the current repo wont be maintained for much longer.

I believe these problems could potentially scare users and developers away.

Begin by reproducing the calculators, Phone catalog, hello world, acalc build, and Todoapp DAO tutorial linked in the issue. Document which demos and tutorial steps work, record the observed build and persistence failures, and clarify the maintenance status of the current repository versus foam2.
