Update Card-Jitsu belt progression system to be accurate to the original Club Penguin (#95)

* change ninja progress system

* make it so ranking up does not reset your progress

* make losing against sensei give you experience

* remove rank speed from card-jitsu

* move get_percentage_to_next_belt

* add autocorrection to card-jitsu exp if it is not proper to the rank

* fix typo

* change the correction for card-jitsu exp
