OverUsed Axe V3

Third version of my OverUsed Axe skin. Looks good.

Improvements based on community feedback: - softened phong shading - improved textures and bumpmap - added a new custom griptape (see below) - included a new menu image

The Griptape was originally developed by 90SK, who kindly allowed me to use its modified version and helped me with the SDK Model viewer used for the in-game menu weapon thumbnails.

Therefore, I'd like to dedicate this skin to 90SK. You've really helped me, man.

EDIT: In the next V4, the use of griptape (which will get improved) will become an option. Also, the wood will be made more "overused" if possible. Coming soon.
