Filling Out Classes

I added everything I could think of that the classes would need by
default.
Dynamic Commands

The game will now properly generate dynamic commands for all the exits,
containers, and mobs in any given room.
Mob Loading

It's now possible to create new mobs in the XML and to add mobs to
rooms.  Most likely this is all we'll do with mobs until after the
JustyVenture.
Forgotten Tag

Forgot to make it so that it would actually allow you to add the mobs
using the <Mobs> tag in XML.
XML Exits and Containers

I made it possible to actually add exits and containers within rooms in
the XML.  I also added a couple of properties to the Exit and Container
classes, and fixed a small bug in each.
Improving Dynamic Commands

I fixed dynamic commands so that a dynamic command can effectively have
multiple subjects.  I also added the ability to use
@container(ContainerName); and @exit(ExitName); commands.  Finally, I
fixed a bug where it was looking to see if the container was locked
rather than unlocked.
Temp JustinTime Commands

I'm just making it possible to look at any of the 4 types of objects
you encounter using our temporary JustinTime interface.
