[Openicc] New OPENICC_automatic_generated metadata key

[Richard Hughes]

Hey, someone pointed me at the following commit:

commit 1d89d57788d15338c69dac86be5df2b9920d2ca4
Author: Kai-Uwe Behrmann <ku.b at gmx.de>

    * [oyX1]: add OPENICC_automatic_generated meta key
        .. and set to a value of "1" for automatic generated fallback profiles.

Why don't you just use DATA_source=edid like I've been using in colord?
See http://gitorious.org/colord/master/blobs/master/doc/metadata-spec.txt
for the other keys that might also be useful.

Richard.
