[DONE] Access NPC Stats Window

This simply allows you to access the NPC stats window ('@' for player's) through the debug menu or through a speech check in casual conversation.  Both this check and the training request have been moved to a 'disease' like the request to join you is currently handled.  That way you simply have to wait a day or so before asking again.  

EDIT:  You'll notice that the stat window doesn't update after you exit it, the new dialogue appears to simply cover it.  I pulled up player.cpp and output.cpp looking for a way to refresh the background once you exit the menu but I haven't had any luck.  You'll want to add the call around line 3060 in player.cpp... the command isn't refresh() but I can't find anything in output.cpp.
