Campbell Barton 617b45256a BGE Blendfile path bug (use for loading and saving the GameLogic.globalDict)
the original blendfile path wasn't reset when loading new blendfiles.
blenderplayer was ok, but running the BGE from blender would set the blendfile original path and never reset it on loading other blend files.
