Small update - Passives rework and multiple saves

Hi Steve!
This small update is the last update before Steam Fest! At the menu today, making some passives more fun and multiples save system!

Passive changes

Comment from Steve: Some of the passives were not that fun to play or too bad. With this rework, the main idea is to have fruits a bit easier to play with a more combo-friendly passive (Passive of the sea) and globally make both Celestials and Fruits a bit easier to play

Passive of the debris:
Old effect: Every Celestial generates 1-4 Asteroids when created
New effect: Every Celestial gives twice more points when combining but generates 1-4 Asteroids when created

Passive of the asteroid:
Old effect: When created, Black Hole generates 50 asteroids
New effect: When created, Black Hole generates 99 asteroids

Passive of the traffic light
Old effect: Deleters give incremental points
New effect: Wheels can now be destroyed for 3 deleters

Passive of the sea:
Old effect: When a Whale is created, generate one of each fruit
New effect: When an animal eats a fruit, generates either a cherry, a strawberry, a grape or an apple
Comment from Steve: Passive of the sea + passive of the Snake = FUN

Multiple saves

The game now has 3 save slots, by default (and your old save) is Save A but you can change save in the settings.
Also, there is a confirmation button if you want to delete your active save
