Build 42 support.

Fixed a rare bug where the trait could be removed before applying the effect if it was added via admin abuse.

Fixed Infinite Cold applying when it shouldn't.

Refactored restore cold event.

The Infinite Cold setting now works properly as a minimum value.

Mod now periodically checks if the trait exists so that you can have the effects if you add the trait mid-game. The trait will be automatically removed once the Cold strength reaches 0.

If Infinite Cold is enabled, removing the trait also removes the permanent sickness, since it checks if the trait exists to reapply the sickness effect.

Improved sandbox descriptions.
