New name, easy mode, new levels, new bonus

I renamed the project to “breakout 71” to make it easier to find. I’ll rename it on the other platforms too. After playtesting with my family last week, i’ve added an easy mode (the starting bonus is always “slower ball”) and a color blind mode (bonuses that require color distinction are removed from the pool). I’ve added one more such bonus, “Color pierce” which lets you pierce all bricks that are of the current color of the ball. It works well with “Single color streak” and “Coins stain bricks”. Also, the color white is now behaving like all other colors.
