Sprite Object pixel coordinate snapping in pixel mode

[TravisGesslein]

When animations in Spriter are created with pixel mode enabled, a pixel_mode=1 is added to the xml/json output as a flag in the spriter_data tag and (just like in the editor), all coordinates of sprite objects should be snapped to the closest pixel, which I think is not the case at the moment (I often get sprite object positions with some fractional parts).
