Breadcrumb's Awesome NPC Guard Shop

Breadcrumb's Awesome NPC Guard Shop 1.0.3

This Bounty script is now under the Public Domain! That means you are free to do whatever you want with it! Cool right??
I forgot to remove a line of code that flags a player with something that they were already flagged with, causing them to be flagged twice. This new version fixes that :)
This adds a new inventory that will be opened when a player tries to remove a Guard to make sure the player meant to do this action. It will ask the player whether or not they actually want to remove the Guard, just in case the player accidentally pressed the button.

Also, updated a bug in a mechanism name (displaywas still display_name)
