Some changes to the corpse-behaviour:
For corpsedragging, it takes one second from when you move until the corpse
is fully pulled into the room. If you move again, before this happens (before
the message 'you struggle to....') you stop dragging. This solution was much
better than making a delay a la 'track' I hope.
For hanging and beheading, there is a 5 second spinning-wheel delay before
the command is actually executed. As usual, you can cancel it by hitting
Alignment isn't changed due to the act of hanging for good races anymore.
Names are only shown for heads and corpses above level 20.
