So we've got this overlay cap of like 100 right? Prevents OOMs
But right now if you overrun it we have no way of knowing how you got
there, so we just end up with no info.
This pr solves that, by adding a printout of icon-icon_state-dir =
amount for each apperance.
Note, we are basically cheating by typing these overlay members as
mutable apperance, they can be just normal appearances, which we don't
have an accessible type for. Fortunately we can cheat.
Oh and if you overflow the limit you get the error overlay applied to
you, for sniks
