fix and merchant

im playing a little with the framerate and hitboxes so things will be a little faster now

merchant is added, it has a lot of range, low damage, low atkspeed, low health but the debuff richer

richer multplies the actual gold from the attacked unit by 1.05 per hit

so if a unit gives 1 gold -> 1.05 on the first hit

on the second hit will be 1.05*1.05 -> 1.10

and so on
