* Fix bump mapping issue that was there since the beginning of time ... flipping normal.y only worked for pond_normal.png texture and IS NOT CORRECT in most cases. Now the texture itself has been adjusted to be correct while the flipping of normal.y removed
* Fix crash when playing sound in simpleInitApp()
* Fix issue where Spatial.setModelBound() would do absolutely nothing
* Skies created via SkyFactory now don't suffer from "premature culling" bug
