Corrected typos, added flags

I've corrected some typos I noticed. You will no longer regard an insturment, apropos as that typo may be. Oh well.

I also added some flags so you can no longer go clothes shopping, then pick up a DVD player, then shop for some clothes, then buy a thing to play DVDs, then purchase a shirt... That I didn't do that before I published the original was an unfortunate oversight.

Also changed a few words and added like two sentences.

Re-reading this thing makes me wonder how to edit it, since it seems pretty decent and self-contained, but at the same time I'd like to expand each node as organically as I can and flesh out the whole thing a lot better... Maybe I'll write more nodes and have the game randomly decide what options will be available. Or maybe you'll just have to suffer through an even longer day. But you'll be fine. Not like you're dying or anything.
