WIMPY sets your wimpy value. When your character takes damage
that reduces your hit points below your wimpy value, you will automatically
attempt to flee.
You will only flee if your character is not in a wait state -- i.e.
has not been using combat commands like cast, trip and bash, and has not
been tripped or bash by an enemy.
If a direction is specified, this is the first direction you will try
to run in.
If the room has no exit in that direction, another one will be chosen
at random.
Specifying a direction of 'none' or 'random' causes you to flee in
a random direction.
WIMPY with no argument sets your wimpy value to 20% of your maximum hit points. Some monsters are wimpy.
