    Allow force insert in SqliteModelProvider.Save ().
    
    Adds a Save () overload to SqliteModelProvider which takes a second boolean
    parameter to cause a forced insert.
    
    This is needed for cases where you want to preinitialize the primary key to a
    certain value. Simply calling Save () would cause the model provider to think
    that this is an existing object, causing an update to happen. Result: object
    not saved.
    
    Example use case:
    
        private class CacheParameters
        {
            [DatabaseColumn(Constraints = DatabaseColumnConstraints.PrimaryKey)]
            public int CacheId { get; set; }
    
            [DatabaseColumn]
            public string Parameters { get; set; }
        }
    
    In this class, the CacheId parameter is set to match the id of objects in
    another table. Without the overload, there is no way to save it.
