v.a.2.0.10: "graphics.lua", "spiral.jpg", more OO in player

Created "graphics.lua" file, handles background image "spiral.jpg", will handle GUI.
Created .updateLib and .drawLib system in "playerdata.lua".  Now when methods change in player objects, they pull it from themselves, not their "refObj" function.  The "refObj" functions are now parameter-less.
