-thanks to Pokémon Katsu for idea-
a better leveling system
- Pokémon that are in the level range of 1-15, will take ONE battle to increase a level.
- Pokémon that are in the level range of 16-50, will take TWO battles to increase a level.
- Pokémon that are in the level ranges of 51-100, will take THREE battles to increase a level.
