Added integrationtests for importing .soil files and creating PipingProfile (kernel input) from it. Changed type of PipingSoilLayer.IsAquifer from bool to double, as this is the type which is saved to the database. Transforming the double to a boolean is now handled in hte PipingProfileCreator. Fixed bug for when database contains no property values.
