/* the ordering of this is actually doesn't make a difference
* However, for ease of use, new entries should go at the end
* so those people that debug the code that get used to something
* being in the location 4 don't get confused.
*
* The ordering in save_name, use_name, nonuse_name.
* save_name is the name used to load/save it from files. It should
* match that of the doc/Developers/objects. The only
* real limitation is that it shouldn't have spaces or other characters
* that may mess up the match code. It must also start with body_
* use_name is how we describe the location if we can use it.
* nonuse_name is how we describe it if we can't use it. I think
* the values below will make it pretty clear how those work out
* They are basically there to make life a little easier - if a character
* examines an item and it says it goes on 'your arm', its pretty clear
* they can use it. See the last sample (commented out) for a dragon
* Note that using the term 'human' may not be very accurate, humanoid
* may be better.
* Basically, for the use/nonuse, the code does something like:
* "This item goes %s\n", with the use/nonuse values filling in the %s
