I have removed all duplicated commands such as wimpy -> change wimpy, change
title etc and they now all under the 'change' command. Type change to see
the complete list of them.
Ghosts and bashing: this is a tricky issue but for now ghost not morphed into
some hard form will be bashable only if he wears any type of clothes/armor
on some logically selected bodyparts. So this means a ghost wielding an oak
staff and wearing boots and gloves won't be bashable, but a ghost with a
buckler or a hauberk work will be. Expect some misc tunes in the future.
Latest bug with bash fixed, those who experienced it know, those who didn't
are just a lucky bystanders.
