ColorMunki Smile

I’ve just purchased a┬áColorMunki Smile so I can write a native colord driver for the i1 display class of hardware. I’ll base this on the Argyll CMS driver which is also GPLv2+ and this will mean we can get faster and more reliable readings by not spawning /usr/bin/spotread and trying to screen scrape the output. It also means we can support the newer LED backlights in the client UIs, which the smile supports.
