Make GS Ball event repeatable

Browse Source 
With these changes, libpokemegb will remove an existing GS Ball from the
players' inventory and reset all GS ball related event flags before
activating the event.

This basically fixes up saves which used earlier versions of PokeMe64
that only gave you the item without triggering the event. (By removing
the existing GS Ball item, it prevents the
need to create a new save in order to unlock the gs ball event
for the users who were so nice to test these earlier builds)

As an added bonus, this makes the GS Ball event entirely repeatable
(which is actually great). You just need to use PokeMe64 everytime to make the
event repeat from the start..
