Added missing EF and SQLite references to the Application.Ringtoets.csproj: - This was done for clarity sake, because the app.config file depends on these references -- Note that the solution still worked without explicitly adding these references, because it was build and put together in a single folder with all the other dependencies that are dependent on EF and SQLite. As a consequence, EF and SQLite was always present when running the solution.
