#Very Simple Item Menu Edit
#Version 1,0
#June 6, 2014
#By smallhobbit (or lemongreen)
#--------------------------------------------------------------------------
A simple edit to the item menu so it only shows Items and Key Items as well as
gets rid of the Help Text; also, only regular Items have numbers. Supposed to
emulate the item menu from "Mad Father"

Just paste it in above Main and it'll work. (though probably not with other
Item menu changing scripts)
