Partially reverted the skybox changes, such that now only a right/left texture exchange is needed. Skyboxes are still correctly oriented and other tools are still compatible.

  - the base class for nearly all Irrlicht classes has been renamed from IUnknown to IReferenceCounted
 
- - Fixed Skybox texture orientations. They are now displayed non-flipped. Existing skyboxes have to be changed, though. Echange left and right texture and rotate up-texture 270 degrees clockwise, and down-texture 90 degrees clockwise. Textures from Terragen and other tools can be used directly, now.

  - Added ITexture::isRenderTarget()
