armorstatus, and terrainstatus
This adds three special status items to show at a glance what the hero
is wielding, wearing, and standing on.
Each of the three items has its own boolean option rather than try to
fix them in with the existing opttional status conditions. After a
lot of testing, I think the weapon and armor ones will prove useful
but the terrain one probably won't be.
Presently it is implemented for tty and curses. When I developed it
six years ago, it was also working for X11 but I'm not able to test
the resurrection of that part so have left it out.
