The board CAN'T render the snake yet (not the actual object). Need to fix it to be synchronizable with image on board
Changed the key enum members to have prefix Key_ to prevent name conflicts
Added way to convert Direction to Coordinate Change
Snake now knows about bends in its tail
Peg objects now know what class they are of. They use an emun to ID themselves
Board now knows how to handle snake. It uses information from Snake class to render it on screen
Updated project to no longer show SIGNED/UNSIGNED mismatch and (DOUBLE -> INT) conversion warnings.
