Added ability to change sprites and the change shows up on networked games
CollisionBoxs now scale when entity scales on X and Y
autoUpdate field in ObjectIO NetVar and NetClass now set to true by default
The way Entity and Sprite draw images are changed.

Sprite now draws directly to Graphics object, completely skipping drawing
through the use of GameBoard. Becuase of this, the location of the image
being drawn should now be relative to the origin of the screen instead of the
origin of the GameBoard.
removed updateOnNetwork function because it was no longer needed
