Support for composite primary keys #32

Regular primary keys are easy:

class Whatever {
    [PrimaryKey]
    int Id {get;set;}
    ...
}

However, it's legal (and often desirable) to have a primary key that consists 
of more than one column:

class Whatever {
    [PrimaryKey]
    int ForeignKey {get;set;}
    [PrimaryKey]
    int LocalKey {get;set;}
    ...
}

This currently throws an exception, but it would be nice if it automatically 
wrote the proper query:

    CREATE TABLE Whatever (
        ForeignKey int,
        LocalKey int,
        CONSTRAINT pk PRIMARY KEY (ForeignKey, LocalKey)
    )
