Minor annoyances

I've fixed/changed a couple of things that were mildly annoying to me.

1. "sm. cardboard box" -> "cardboard box". There is no large or otherwise differently sized cardboard box in the game, so why specify this one as "sm."? Also, the shortening of small to sm. seems unnecessary. This is also more consistent with other containers, e.g. we have small waterskin, waterskin and large waterskin (no "sm. waterskin"!). If needed, it's easy to add cardboard boxes of different sizes.

2. "frozen" -> "uncooked". Frozen really isn't the best word in this context I think, unless there's plans for adding a freezing/thawing mechanic. Frozen food wouldn't stay frozen for very long in the apocalypse, and as it stands now you can carry a frozen burrito around all summer and it never stops being "frozen" (I guess it might rot, I don't remember, but it will still be named "frozen"). It also fits really well with the already existing descriptions of the frozen foods (e.g. "Cook it to make it tasty!"). And the cooked counterparts of the frozen stuff is called cooked, so uncooked seems to me to be a better descriptor than frozen.

I changed "frozen dinner" to "uncooked TV dinner", since its cooked counterpart is already called "cooked TV dinner".

Feel free to correct me if I'm wrong about anything (I'm not American, so some of the things (esp. some of the comestibles) in the game are foreign/unknown to me).
