Level compiler creates correct novel with supplied name

Before this commit, the name of a novel in the level files was ignored for
setting novelidx. But the name was set nevertheless, so you got a named novel
that showed quotes from a different novel.

Now, 'des.object({ id = "novel", name="Raising Steam"});' will work as
expected.
