Split raw RGB565 into RGB565LE/RGB565BE/BGR565LE/BGR565BE

This change splits the raw file importing to handle the two different
endiannesses natively. This fixes a bug where the same image would
import different on different CPUs or even on different operating
systems on the same CPU. This also adds the ability to directly open
BRG565 files from the raw file import dialog.
