Supporting OpenIccDirectoryProposal

[Richard Hughes <hughsient gmail com>]

OpenIccDirectoryProposal is a proposal to make the main CMMs in Linux
and UNIX adhere to a common directory spec. I stumbled on it this
morning, and agree with what it's trying to achieve. As such, I've
committed two changes to GCM in git master (not gnome-2-30) to adhere
to this spec:

    Use the common data path from OpenIccDirectoryProposal

    No migration is required, the old location is searched as well.

    Use the common configuration path from OpenIccDirectoryProposal

    You will need to rename ~/.config/gnome-color-manager to
    ~/.config/color if you want to re-use your old configuration

You can see from the last commit a rename is required if you don't
want to re-assign all your profiles. I might do that automatically
closer to the 2.31.2 release if there are people that file bugs,
although it would be upsetting to run a GCM from a checkout which made
your system GCM stop working.

Maybe I can just put it in the release notes.

Richard.
