I've just added a trivial line to the spec file installing the udev rules from the package. This is important as from F12 onwards HAL is not managing the ACLs, and as such the color calibration devices are only available as the root user.

This is just tested by me, but is a totally trivial change to make the devices have the same permissions they did in F11. This package isn't on any livecd and such is low risk, and without tagging the devices are only available as the root user. Thanks for considering.
