* This sets up a basic trap on a lock. The trap will be triggered when

* @param difficulty skill bonus needed to avoid triggering the trap
* @param trigger "unlock", "pick, "open", for which activities should
* trigger the trap.
* @param description a description of the trap for someone who looks at
it.
* @param message The message to be displayed to the player. If it's an array
* the first index will be printed to the player the second
* to the room.
* @param effect the effect to be added to the trigerer. If the effect is an
* int the players hps will be reduced by that amount. If it is
* a string that effect will be added to the player, if it's an
* array the first index will be treated as the effect the rest
* as parameters to the effect.
