Small Changes

-Changed FixedTimeStep in project settings to .01 instead of .02,
smoothing out ball movement(it looked choppy when you were moving in the
same direction as the ball)
-Changed Block script so anything can damage the block, not just
collisions
-Changed Paddle script to completely stop moving past the walls(before
it just moved it back a bit, which made it flicker in and out of the
wall a bit)
-Added ExplodingBlock script
