Consolidated the views into one view

TitleView and GameView are now implemented as Drawers and Inputs that
  SweetSmushView uses
Game Drawing fixes

Game board now draws
Had to re-order where GraphicMgr was initialized, now done right before
  game is created when switching from title to game
Updated piece drawing to draw spaced apart properly
Each piece now keeps track of it's spot on the board
Gray background drawn on game board
Added GameHolder interface so that the game can change without
  having to recreate the drawer/input
