GUIShop / HumanNPC Distance check conflict

We have a conflict with HumanNPC's distance checks 

On line 1935 inside HumanNPC 

var hitpoints = Physics.RaycastAll(new Ray(player.transform.position + eyesPosition, currentRot * Vector3.forward), 5f, playerLayer);

I need the 5f variable to set as a changeable option for people either inside the data file setup you have or in a config style system.

Otherwise, I will never be able to resolve this bug between our plugins that satisfies the players/users.

Config option added be warned if users change this it will effect all the npc's radius checks when clicking USE on the npc.
