Changed the way that items & monsters are created

Took out the ItemDuplicator way of creating items and monsters.

At the moment, quotes and descriptions are not added to entities from
their quotes file.  Will have to modify this to work with the new code
and add it back in.
Quotes added back in

Adjusted the quotes code so that it works with the new item creation
code.
Removed some useless stuff

Removed some commented out code and some unused methods created when
changing the item creation and quotes.
Removed more useless stuff

Found move lines that were commented out and unused.  Deleted them.
