[Openicc] Open Source compatible AdobeRGB profile

[Lars Borg]

Adobe provided the Adobe RGB spec to enable vendors to make 
compatible profiles without violating Adobe's trademark or copyright.
Make sure you use the exact numbers as provided in the spec, 
otherwise obviously you're not compatible. This includes using the 
same format version number.
Of course, the file name, profile description, and copyright, shall 
be different from the ones used by Adobe. The spec suggests how you 
can name a compatible profile.

One way to weed out incompatible profiles is to use your new profile 
in an image, and set Photoshop's color settings to Adobe RGB and to 
report mismatches on open. On opening the image, Photoshop checks the 
colorimetry of the two profiles.
