Fixed rotation bug

There was a bug with GuiObjectView causing the view to rotate around the wrong axis instead of the center of the object that was loaded.
A fix was posted on the GarageGames forums a while back, but never seems to have made its way in to the repo.

Merge remote-tracking branch 'origin/Fix-GuiObjectView' into HydroSim
