Shady Updates - DEC17

Minor updates:

• Some new visuals for the pieces to make them standout a bit more from the background
• Increased the size of the circular piece - a bit more of a pain in the butt now
• made a very slight increase to mass and damp on pieces that are "set"
• added [a] and [d] keystroke for rotation of pieces for smooth rotation, mousewheel scrolling still works for clicky/precise rotation
• crushed a new record on the leaderboard so you chumps don't think you can mess with the king.
