Added a success/failure for book addition to data base,
will eventually need to add a nice javascript to confirm correct book
as well as book searches.
added pages for viewing on success/failed library addition
I added books to the user database. It's not pretty,
nor do I think we should use it long term.

I think we shuld store objectId's in the users collection,
this will allow us to quickly find (in a sorted database) all of the
books stored in the library. I may implement this in the next few days
if I have time.
