Major Changes to the core game

Decided to come back to this game and look at my old code. Ended up making some changes and I'm thinking of a couple more.

• Modified the whole game to have the paddle move with mouse movement instead of mouse position.
• Removed set number of levels.
• Added a single scene that randomly auto generate the levels as player progresses base on a set percentage for each type of block.
• Prevented the unbreakable blocks from caging in a random block and prevent the player from destroying it from all angles.
• The ball now moves at a fixed speed so it never slows down nor speed up.
• Added lives to the player.
• The ball will slightly correct it direction randomly depending whenever it doesn't hits a block for more than 2 seconds
