fixed LeastICouldDo

I changed it to a "ArchivedComic"

I think this will work better.  Let me know if there are problems. I also had to make change to the parser because they do date a different way.

Last I don't know what I should do for getAllComicsUrls as it doesn't seem necessary. I just left null.
