GL: Delete code for GL_TEXTURE_RECTANGLE_ARB in case of non-pow2 textures - all modern GFX cards that can run Dolphin should support non-pow2 textures anyway. This removes some complexity and reduces the numbers of pixel shaders that need to be generated in some situations. Also fixes some texture mirroring problems. Let me know if this breaks things on ATI for some reason.
