Greyscale library: * Implement linearisation curve flipping for 1st/2nd Gen iPods (LCD is inverted when backlight is on, so the curve is also inverted). This needs a slight extension of is_backlight_on() functionality in the core. * Thorough recalibration of all reachable greyscale targets, and #ifdef cleanup. * Reduce on-target gamma a bit, because the displayable contrast range of a monochrome/greyscale isn't that high.
