Fix hardware mipmap generation for cube maps

Browse Source 
I was getting a black image when enabling hardware mipmap generation on cubemaps. I believe the problem is that the base Texture class is hard coding GL_TEXTURE_2D when enabling mipmap generation, instead of using the target type from the derived class.
