Title: Added flicker tint

I just added something similar to powerUp colors index, except using a
transparent color. There's no need for spriteFlickerAnimation method. The isHit color
index is part of the GameCharacter class and the Hero class references
it. We could change the timing of the flicker. I did this late at night and I think the timing is the same as powerup time.
