No more exceptions for improper IDs

When you hit a key for an id which isn't proper (like a capital letter)
it now does nothing instead of throwing an exception.
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.
Capslock message and wizard mode

Hitting a capital version of an existing ID gives a warning in the
console about capslock. Shift-W enters wizard mode, with tons of
hp/attack/nutrition/etc.
Added wizard control to control help text

Added the new wizard command to help command list.
Show equip status in inventory

Now when you look at weapons or armour in inventory it notes which ones
are equipped.
