Bugfixes

Bugfixes:

1) Sprites (Teeth, Shadows in transitions), always on the right layers.

2) Rare upgrades now have a 20% chance of spawn instead of 80% as it should have been.

3) Statistics (Hp and Points for eating) of big and small food were mixed up, now everything is working correctly.

4) Gemini is now a fully functional character (Leveling is no longer reset between levels, and objects do not interact with Gemini)

5) Now upgrades are queued up, and you can't get only 1 upgrade for 2-3 levels taken at once.

6) The health bar now does not disappear from Gemini 2 during sleep.
