[Scribus] Argyll CMS is updated

[Paraplegic Racehorse]

Argyll CMS gets a bump to 0.52. From the FreshMeat page:

*"Changes:*
A new "dispcal" utility for calibrating displays was included along with
"refine", a tool intended to support the improvement of proofing color
matches. Improvements were made to the speed and accuracy of general
profiling."

Has anyone made use of Argyll or is it still considered too much Beta?
