Updated the sf2dlib and sftdlib; Added the gfx.color.hex() function; Added the New3DS CPU mode control.

As the color order of the sf2dlib changed, you have to change it in your code, or use the color.hex() function.
To fix the problems, just change "0xRRGGBBAA" to "0xAABBGGRR".
Also, the shader compiler changed to Picasso, so you'll need it in order to compile.
