Minor change to wands, staves, and scrolls

Date:Mon Mar 27 20:02:09 2006
You should now be able to use wands, scrolls, and staves like "normal"
spells with respect to their targets.

For example, that means that a scroll with fireball can be used as
"recite scroll" to hit your current victim, and a wand of bless can be
used on objects, etc.

I don't think any backwards-incompatible changes were made, but please
look out for bugs.
