updated TODO list
Added a wizzard NPC. NPCs are still pretty useless.
play_game.py now passes the debug state to dungeon_master

Also when in debug mode CTRL-C / CTRL-D still work.
Added comments and npc.py is now imported on 'import *'
minor changes to item.py
DungeonMaster.out and DungeonMaster.log should be used now.

out() is for printing
log() is for debug messages.

Added goto <room_name> and roominfo actions for better state info while inside
the game.
updated IT room and first pass on integrating NPCs.
