Custom PPSSPP shaders

[LunaMoo]

Well I was only checking my shader against old amd gpu's with amd gpu shader analyzer, thinking if it works on that bs it works on everything, apparently I was wrong. Now I forced GLSL #version 100 and corrected all errors I could find which came along new stuff I added. I think the only case where #version 100 of GLSL might be required that ppsspp supports would be GLES 2.0 devices, meaning mostly older android hardware.

Either way my shader from first post returns back to supporting GLSL #version 100 now, meaning should work on anything unless the driver is horribly broken, so just redownload.
