GSdx: Anisotropic Filtering.

Adds anisotropic texture filtering (1x-16x) to the hardware settings. Enhances the visual quality of textures that are at oblique viewing angles.

Anisotropic filtering is automatically disabled if: 8-bit textures are enabled.

GSdx: Anisotropic Filtering.

Fixes a small oversight on my part. Which was setting the maximum anisotropy to (0,1,2,3,4) respectively, instead of (1,2,4,8,16). So when you selected x16 for example, you were actually only getting x4 >.>

Corrected now, and you will be getting the full x16 when selected :)
