S BAT 2 beta 2.0 now with fancy retina display

Sorry for lack of updates. Lost some momentum last few weeks (mainly due to Warhammer 40k: Space Marine and Dragon Age…). I got me a fancy iPhone 4S and got the artwork up-converted for retina display. Cocos2d made it relatively easy. Had one issue with z axis, but it wasn’t too hard to track down. As far as I can remember, the only change for this is retina. So no changelog this time.
