- Major update to the viewer. A little bit buggy now, but I'll fix that

- 2/3 of the viewer code are no wrapped in helper classes
- ByteSwap.h header added 
- Bugfix in the 3DS loader: Texture blend mode was read incorrectly
- Bugfix in the X-Loader. Assets with specular_exp == 0 use gouraud lighting now
- Added new helper functions to MaterialHelper 
- Added aiMaterialGetTexture() function to allow easy access to all properties of a texture
