// HIDDEN UPLINK - Can be stored in anything but the host item has to have a trigger for it.
/* How to create an uplink in 3 easy steps!

 1. All obj/item 's have a hidden_uplink var. By default it's null. Give the item one with "new(src)", it must be in it's contents. Feel free to add "uses".

 2. Code in the triggers. Use check_trigger for this, I recommend closing the item's menu with "usr << browse(null, "window=windowname") if it returns true.
 The var/value is the value that will be compared with the var/target. If they are equal it will activate the menu.

 3. If you want the menu to stay until the users locks his uplink, add an active_uplink_check(mob/user as mob) in your interact/attack_hand proc.
 Then check if it's true, if true return. This will stop the normal menu appearing and will instead show the uplink menu.
