Scaling trainer evolutions by Leilou

I just wrote it into a new script ... but anywhere outside of any class works
================================================
def evolvePokemonSilent(pokemon)
  newspecies=pbCheckEvolution(pokemon)
  if newspecies == -1
    return pokemon
  end
  newspeciesname=PBSpecies.getName(newspecies)
  oldspeciesname = pokemon.name
  pokemon.species=newspecies
  pokemon.name=newspeciesname if pokemon.name==oldspeciesname
  pokemon.calcStats
  return pokemon
end
================================================

Then you go to where you want to do the evolution check ... i did it inPTrainer_NPCTrainers script in pbLoadTrainer method
right before the last line of the method
================================================
return success ? [opponent,items,party] : nil
================================================

insert this block of code here
================================================
  #check every pokemon if it can evolve and evolve it
  for i in 0 ... party.length
    while party[i] && (pbCheckEvolution(party[i]) > -1) do
      party[i] = evolvePokemonSilent(party[i])
    end
  end
================================================

it works on clean essentials 16.2
it's evolve the pokemon multiple times
like bulbasaur into venisaur if the conditions are met
