Have creatures die from torture

[mefistotelis]

Originally reported on Google Code with ID 505

In DK there are a few rooms very overpowered: Prison, Torture chamber, Graveyard and
Scavenger room as they allow the player to become more powerful from fighting creatures.
Map makes either have to disable these rooms – no fun – or risk making the player far
too powerful and going over the creature limit.

An enhancement would be for campaign or mapmakers to nerf creature converting. Right
now if you keep the health of a torture victim up, eventually he will convert. To balance
the power of this room, and to help with the creature limit a possible torture outcome
should be the premature death of the victim.
And also for not every kill to result in a ghost.

In the level script add a few variables:

SET_TORTURE_DEATH_CHANCE (#) – At 0 all creature will eventually get broken, at 100
all creatures get killed from torture. At 50 half the creatures die, the other half
get broken.
SET_TORTURE_CONVERT_CHANCE (#) –  Like currently in the rules.cfg. The percentage of
creatures that WHEN BROKEN join the player. 
SET_TORTURE_GHOST_CHANCE (#) – What the GhostConvertChance currently is from the rules.cfg,
but in the level script and renamed to be consistent with the others. How often a ghost
appears when a creature dies in torture caused by either running out of health or straight
up die from torture.
