Understand the base libraries!

I think a good tip to any new Hugo programmer is to become familiar with the Hugo library files. I always learn something new every time I look at the code, whether it’s the specifics on how certain processing works, or the fact that there are basic verb implementations that most players probably won’t even try (like “wait for NPC” to spend turns until a roving NPC enters the room, or “i/inv tall” and “i/inv wide” to change the inventory listng style).
